- Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP
(reporting IFM_LOOP based on BMCR_LOOP is left in place though as
it might provide useful for debugging). For most mii(4) drivers it
was unclear whether the PHYs driven by them actually support
loopback or not. Moreover, typically loopback mode also needs to
be activated on the MAC, which none of the Ethernet drivers using
mii(4) implements. Given that loopback media has no real use (and
obviously hardly had a chance to actually work) besides for driver
development (which just loopback mode should be sufficient for
though, i.e one doesn't necessary need support for loopback media)
support for it is just dropped as both NetBSD and OpenBSD already
did quite some time ago.
- Let mii_phy_add_media() also announce the support of IFM_NONE.
- Restructure the PHY entry points to use a structure of entry points
instead of discrete function pointers, and extend this to include
a "reset" entry point. Make sure any PHY-specific reset routine is
always used, and provide one for lxtphy(4) which disables MII
interrupts (as is done for a few other PHYs we have drivers for).
This includes changing NIC drivers which previously just called the
generic mii_phy_reset() to now actually call the PHY-specific reset
routine, which might be crucial in some cases. While at it, the
redundant checks in these NIC drivers for mii->mii_instance not being
zero before calling the reset routines were removed because as soon
as one PHY driver attaches mii->mii_instance is incremented and we
hardly can end up in their media change callbacks etc if no PHY driver
has attached as mii_attach() would have failed in that case and not
attach a miibus(4) instance.
Consequently, NIC drivers now no longer should call mii_phy_reset()
directly, so it was removed from EXPORT_SYMS.
- Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe().
The purpose of that function is to perform the common steps to attach
a PHY driver instance and to hook it up to the miibus(4) instance and to
optionally also handle the probing, addition and initialization of the
supported media. So all a PHY driver without any special requirements
has to do in its bus attach method is to call mii_phy_dev_attach()
along with PHY-specific MIIF_* flags, a pointer to its PHY functions
and the add_media set to one. All PHY drivers were updated to take
advantage of mii_phy_dev_attach() as appropriate. Along with these
changes the capability mask was added to the mii_softc structure so
PHY drivers taking advantage of mii_phy_dev_attach() but still
handling media on their own do not need to fiddle with the MII attach
arguments anyway.
- Keep track of the PHY offset in the mii_softc structure. This is done
for compatibility with NetBSD/OpenBSD.
- Keep track of the PHY's OUI, model and revision in the mii_softc
structure. Several PHY drivers require this information also after
attaching and previously had to wrap their own softc around mii_softc.
NetBSD/OpenBSD also keep track of the model and revision on their
mii_softc structure. All PHY drivers were updated to take advantage
as appropriate.
- Convert the mebers of the MII data structure to unsigned where
appropriate. This is partly inspired by NetBSD/OpenBSD.
- According to IEEE 802.3-2002 the bits actually have to be reversed
when mapping an OUI to the MII ID registers. All PHY drivers and
miidevs where changed as necessary. Actually this now again allows to
largely share miidevs with NetBSD, which fixed this problem already
9 years ago. Consequently miidevs was synced as far as possible.
- Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that
weren't explicitly converted to support flow control before. It's
unclear whether flow control actually works with these but typically
it should and their net behavior should be more correct with these
changes in place than without if the MAC driver sets MIIF_DOPAUSE.

Use a private callout timer to drive the transmit watchdog instead of using
if_watchdog and if_timer. The driver already contained an optional stats
timer that individual attachments could use to provide a 'tick' event. The
stats timer only ran if the tick function pointer was non-NULL and the
attachment's tick routine had to call callout_reset(), etc. Now the driver
always schedules a stat timer and manages the callout_reset() internally.
This timer is used to drive the watchdog and will also call the attachment's
'tick' handler if one is provided.

Minor tweaks in the names to match the chips more closely.

Minor DLINK DL100xx support tweaks:

The DIROUT bit difference between the 19 and 22 is annoying. We can
set both bits on both parts without ill effect. Use this trick to
simplify the code.

The DELAYS in the MII bus bit-bang code for the DL100xx parts aren't
needed. Eliminate them.

The AX88190 has 64k of external SRAM, of which 62k can be used for
packet data. However, the AX88190A moves this on-chip and reduces it
to the more traditional 16k from 16k-32k. The AX88790 follows the
'190A. Probe memory above 32k to see which flavor of the '190 we have
and use the extra memory if we have it.

Eliminate the kludgy read eeprom for the ID code. It really is just a
memory read at location 0x400, so just use that instead. Makes the
code easier to understand as well as eliminates some magic numbers.

Force an autonegotiation at attach time for all the attached PHYs for
ed cards. There's a number of minor nits in a lot of the PHYs on the
PC Cards that use the Axis AX88190 or DLink DL10019 and DL10022 chips.
Forcing the autonegotiation doesn't seem to cause problems on the
cards that have sane PHYs, but makes several cards I have work without
further workarounds.

I'm not 100% sure that kicking the PHY and resetting them is the right
thing to do on the media change callback. Other NICs seem to need
this and do similar things.

Add additional data on the MIIBUS WTF that I committed earlier.

It turns out that the initialization is required since it sets up the
readout of the MAC address.
The 10ms delay was really needed. Ooops.

o Minor tweaks to the AX88x90 probe routine, mostly related to comments.
o Don't run through the register initialization in the read mac routine
for the AX88x90. It duplicates other stuff that we do.
o Eliminate the 10ms delay after we reset the AX88x90. We already wait for
the appropriate bits to indicate reset is done.

Go back to filtering all PHY addresses above 16 since at least two
cards still have issues with them. Maybe this is a silicon rev? In
any case, doing the filtering only for the AX88790 for the moment.

Hmmmm... This can't be right... But it looks like the DL100xx chips
don't have one of the clock cycles (the turn cycle) that the AX88x90
chips have. Make this conditional. But this seems totally crazy and
can't possibly be right. Commit the fix for the moment until I can
explore this mystery more deeply.

On the plus side, the DL10022-based cards I have (D-Link DEF-670TXD
and SMC8040TX) work after this fix.

Two fixes:
(1) Delete all children when detaching to keep from adding a phy each
driver reload.
(2) All AX88x90 chips have the RST issue.

This is a major reworking of the AX88x90 support.

o Introduce new chip_type AX88790. There's a few places we need to know the
exact chip for workaronds.
o Explain the AX88190 workaround for the ISR bits being stuck, and don't

experience confirms.
o Fix mii bit-bang read code to read and discard the 'floating' bit.
o Remove empty ed_pccard_ax88x90_mii_reset routine
o Report error from mii_phy_probe
o Don't use ed_probe_Novel_generic for ax88x90 chips. It puts them into
an odd state sometimes. Instead, use a more stream-lined version that
avoids the trouble spots. This was copied and tweaked from the original.
o Move chip reset into its own routine.
o Minor code optimiation on getting MAC address
o Add code for coping with AX88790 cards that are in power down state and

o Remove ugly cap of PHYs at 17.
o For AX88790, we need to set a special bit for accessig phy 16 (the internal

# This fixes the sbdrop panics I was seeing with the Toshiba LANCT00A.

It turns out that the Toshiba LANCT00A PC Card is really like the
Toshiba PCETC ISA card, and even has the same board type code in the
card ID (0x14). So, for this card, call ed_probe_WD80x3_generic after
setting things up apropriately. This makes the card attach and kinda
work (I'm seeing panics in sbdrop). Since history has shown that the
WD80x3 probe routine is dangerous, only do it for this card. Also,
disable the memory range check to make sure it is an valid ISA memory.
I think that it is bogus, but I'm not 100% sure, for these cards.

I removed probing for the WD80x3 in 2005 when I added support for the
AX88x90 and DL100xx cards since none of my cards had ever matched it
and PAO3 removed it and none of the cards in their database died.

It is possible there are other quirks about this card too, since no
other open source OS supports it, or even claims to support it. But
it was a fun half hour hack...

they are from the days before the ne2000 roamed the earth and use a
non-standard hookup (see if_ed_isa or if_ed_cbus for some examples).
Unless I happen to stumble into the right one, these may never work,
but I'm tired of omitting them from commits.

When the miibus for the AX88x90 or TC5299J cards fails to attach, we
would call ed_release_resources() when we should have called
ed_detach() to properly undo the effects of prior calls to
ed_attach(). This would leave a stray ed interface ifnet alive in the
system, which was, well, bad, since we called if_free() on the
underlying memory... Fix the ed_detach routine to cope being called
in this context now.

This should never come up because the miibus is always there. Except

Add a note about why we set this flag prior to attaching the device.
We never set or clear the flag later, only test it. There can be no
races here, but this might be asthetically displeasing to some. Also
note that we may no longer need to have this knob at all as we may be
able to do it with the more sophisticated rc.d scripts we have today I
think the only reason it is there is because we didn't used to allow
its proper setting when configured to get the IP address via DHCP.

I'll note that this would be better handled by using ifmedia for all
ed cards, not just those with a miibus...

# this gets the RTL8019 on a SBC at work fully functional. 6.0 still treats
# the 8019 as a generic NE-2000, so these changes aren't relevant there.

In the ISA case, we call ed_probe_WD80x3 before we call
ed_probe_rtl80x9. In the pci case we call ed_probe_rtl80x9 first. In
the PCI case we were using the correct nic_offset by accident because
softc is initialized to zero. In the isa case we were using the wrong
value by accident, since ed_probe_WD80x3 sets the offset value to
0x10. This lead to the identification routines failing. Fix this
problem by always initalizing the nic_offset and asic_offset before
making ed_{asic,nic}_{in,out}* calls.

Check against 8019 rather than 8029 for reading in the MAC addr since
the former is the ISA part, not the latter.

Emit a warning when a card matches multiple entries in our table. A
number of cards have been discovered to be matching on the strings of
the cis rather than manufacturer/product id for cards we already had a
prod id for. This is a result of getting the list from the NetBSD
driver which also includes the OID for the cards where such a
distinction mattered (since it was tested against the MAC address we
got from the card). Since we do not try to match OIDs, we do not need
the extra entries and they just waste space.

I'm guessing that some of the dlink entires (DE-660, DE-660+) and many
of the corega cards may fall into this boat and can safely be removed.

Go ahead and detach our children in our detach routine. I'm undecided
if we should delete them also or not, but have decided not to do so

I have confirmed with my Epson EEN10B that it needs to look at the

Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt

cause a crash. Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

o eliminate the ED_NO_MIIBUS option. Now, you need miibus to use ed with
pccard. If you have an old ISA or PCI card w/o a miibus, then you'll still
be able to use the ed driver w/o miibus in the kernel. If you have pccard
you'll need mii now. Most pccards these days have miibus, and many
cards have ISSUES if you don't attach miibus. issues I don't want to
constantly rediagnose.
- Add new media_ioctl, mediachg and tick function pointers. The core
driver will call these if they aren't NULL, or return an error if they

When stopping the card, and returning to page 0, it is best if you do

o Attach AX88x90's MII bus to system, and require its presence.
o Reorg the mii code a little, and move more of it into pccard attachment.
o Eliminate ed_pccard_{read,write}_attrmem in favor of a more appropriate

o Update comments to reflect knowledge gained.
o Update how re recognize a NE-2000 ROM. I found a couple of different
datasheets that define the structure of the PROM data, so the code's
old heuristics have been removed, and comments updated to reflect the
structure.
o Eliminate work around for EC2T. It is no longer needed, and was wrong
headed since the EC2T has a Winbound 82C926C in it, not a AX88x90.
o Add copyright to if_ed_pccard.c, since I believe I've re-written more than
3/4 of it.

MFp4: Minor formatting nits in pccard table.

Use smaller names. The "NE2000 PCI Ethernet" is largerly redundant
with edX at pciY. This removes 8*22 bytes from the strings. Not a
huge win, but a cheap one.

MFp4:

Reduce the size of ed a little by removing some CIS based entries (others
likely can be removed too):
o The D-Link DFE-670TXD doesn't need its own entry based on strings.
o The Xircom CompactCard appears to be a TDK design, so list it there by ID
and remove the strings.

Increase the size of ed a little:
o Add support for the Addtron AE-660CT and Addtron AE-660. This is a very
generic NE-2000 clone (so generic that its CIS tags say NE-2000 generic
card!).

The ed driver lock is already held in the mii frobbing routines. Remove
locking from these routines.

Add note about what ED_DEFAULT_MAC_OFFSET applies to

Consistancy is the hobgoblin of small minds:
o DLINK -> DL100XX

Minor reorg of pccard attach code to fix ax88x90 case broken after fixing
dl100xx case.
o We no longer acquire and release resources during attach many times. We now
do it once at the beginning.
o Move setting the resource offsets to just after acquiring the ports in
attach.
o Move ax88x90 code to the end of the file, just after the dl100xx specific
code.
o Rename ed_pccard_Linksys to ed_pccard_dl100xx to reflect the underlying
chipset.
o Pass the ed_product structure into ed_pccard_{dl100xx,ax88x90} and have
those routines test the flags to see if this card should be probed in that
way.
o transition from ed_probe_Novell to ed_probe_Novell_generic since we already
have the resources setup.
o Move use of ed_probe_Novell_generic into ed_pccard_dl100xx to be more
consistant with ax88x90 case.
o simplify the code where we probe for the chipsets

o Expose ed_probe_Novel_generic, it is useful for pccard case.
o Fix a now stale comment. There are likely many others like them, but this
one definitely hasn't been true since DELAY was introduced into the tree.

Fix DL100xx based cards. Don't drop resources. It was approrpiate in
the probe code that this used to be part of, but as part of the
attach, we shouldn't be dropping the resources here.

Also, allocate the proper rid in the ax88x90 setup.

move away from K&R function definitions

Work around a bug I've seen on Linksys EC2T cards. For some reason,
as yet unknown, those cards report their MAC address a byte at a time.
However, other AX88x90 cards report the MAC address a word at a time.
Add a heuristic which looks at the high order bytes of the first 6
words. If they are all '0', assume the card is behaving like the
Linksys EC2T card. Since the default prefix for these cards appears
to be 00:e0:98, this appears to be a safe heuristic. While some cards
have been observed with different prefixes, they all work with this
heuristic.

I'm unsure if this is a bug in the EC2T card, or if it is a bug in the
initialization of the card. No other OS has this heuristic (although
w/o it, the MAC address that is used works).

Go ahead and | in ED_CR_PAGE_0, even though this doesn't change things
at all. It makes the code clearer.

fix a comment comments about why we need to write i/o address to certain
registers.

It turns out that many of the ambicom cards have their CIS resources
listed in different orders. Since it is easy to identify the Modem
resources vs the Ethernet resources by looking at the size, use that
rather than hard coded rids. For such parts, go ahead and guess which
rid we should use based on the size. This guess appears reliable for
the two example cards that I have with different CIS info.

MFp4: kill bogus comment

At some point in the past, we read the PROM by words. Now we read
PROM by bytes. Adjust the extraction of the MAC address from this data
to reflect this change.

This gets the AX88x90 based PC Cards MAC address working again (my
UMAX Ethernet and Linksys EC2T cards now work).

Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address
from driver private storage rather than sometimes being ac_enaddr.

Fix the support for the ax88[17]90 to print the right type, rather
than the generic ne-2000 string. This should have no effect on the
actual support of the parts, just reporting what the part was.

Also, rename a few functins and symbols to reflect a more generic
part support that grew out of the early specific support.

Move the harvesting of the MAC address out of the generic novell probe
and into the bus front ends. For ISA and C-BUS cards, we always need
to grab it. For PC Card, already committed, we need to do some sanity
checking on the data that's in the ROMs before we decide that they are
OK to use. The PC Card code has already been committed and is
independent of this code (which also has to work on NE-1000 cards,
assuming that those cards still work :-).

Move the #defines from edreg to edvar which don't have anything to do
with talking to the hardware.

o It turns out that most of the ne-2000 cards that I have got real unhappy
with the latest changes. They actually have valid ROM data at location
0 of memory, just like a real NE-2000 ISA card. Use this data, if
the ROM passes a few basic tests, as an additional source for the MAC
address. Prefer the CIS over this source, but have it take precidence
over falling back to reading the attribtue memory.
o Minor cleanup of a few devices that we match on based on CIS string.

Rework DL10019/DL10022 support. This tries to reset things in a more

Improve the mining of MAC address from the card:
o Add a fallback location for the MAC address. Most of the early ne2000
PC Cards were built from the same parts, so most of them have the same
address in the CIS to grab the MAC from. Use this address as our
fallback if we don't find anything better.
o Add printf, in bootverbose, noting the MAC addresses that we find along
the way.

# Better sanity checking of the MAC address is needed. Will have to
# investigate using/creating a centralized function to do this as a number
# of other PC Card drivers each have their own ad-hoc tests.

Add comment about MAC mining

Really old PCMCIA cards stored the MAC address in the attribute memory
at some offset. Unlike newer cards, the MAC address wasn't part of
the CIS as a specific FUNCE. These older cards were having their MAC
address show up as 0:2:4:6:8:a because that's what's in the ROM
locations that would be there in a real ne2000.

This patch allows one to specify the offset for the MAC address for
these cards. Specify one for the IBM Ethernet II card, as it is one
that has this problem. One shouldn't specify this unless the MAC
address really isn't in the CIS at all.

Side note: The novell probe likely shouldn't read the MAC address, and
that should be moved to the bus specific attach routine(s), maybe as a
convenience function in if_ed_novell.c.

My IBM Ethernet II (aka Info Mover) now has a believable MAC address.

Diff reduction with p4.

Eliminate the ED_VENDOR_{PCCARD,LINKSYS} types. These cards really
are NOVELL NE2000 with just a tiny quirk that's non vendor specific.
Instead, use the chip_type of DL100XX instead. This is more inline
with how the AX88190 support was added, and seems a little cleaner.

Move enable/disable 16bit access routines into if_ed. Slightly
pessmize the error recover path through edintr by calling these
functions, rather than expanding it inline. This error path already
does a lot in it, so an extra function call will be lost in the noise.
It also happens rarely.

use

Extricate probing of the gwether card (Gateway AT) from the middle of
probing the novell ne[12]000 cards. It should be its own thing, ala
how we do the dl100xx support doing its own thing at the right time.
For the moment, it is just a function, which makes the mainline of the
generic probe easier to follow.

Also, correct a couple of comments that looked wrong.

# there may be a bug in setting up gwether, in that we set
# sc->rec_page_stop based on memsize, rather than sc->mem_size, so if
# these two are different, then the rec_page_stop will be wrong. I'm
# hesitant to fix it without real hardware to test with. Since
# gwether isn't in the hardware list of the man page nor in the commit

Remove an ifdef that's been here for a long time. So long, in fact,

Add goo for alpha too.

The affected cards are the 3Com 3C503, HP LAN+ and SIC (whatever that
is). I couldn't find any of these for sale on ebay, so they are
untested. If you have one of these cards, and send it to me, I'll
ensure that you have no future problems with it...

Minor cleanups as well by using functions rather than cut and paste
code for some probing operations (where the function call overhead is
lost in the noise).

Remove use of kvtop, since they aren't required anymore. This driver
needs to get its memory mapped act together, however, and use bus
space. It doesn't right now.

This reduces the size of if_ed.ko from about 51k to 33k on my laptop.

Since we no longer use kvtop, we no longer need machine/md_var.h

If either ed_probe_Novell or ed_attach returns an error, release the
resources too.

o Remove duplicate LINKSYS ETHERFAST entry.
o The COMBO_ECARD comes in many flavors, it seems, so probe both the DL10019
and the AX88x90 on it. Since this seems to work with no ill effects, maybe
the probing should happen more generally rather than being table driven.
Need to think more about this.
o Remove PCM100 because it is duplicative (the ETHERFAST is the pcm100 and
apparently has the same IDs). It was here for NetBSD because they match
up an expected MAC address OID, but since we don't bother with that, we
don't need to be so finely discriminating.
o Minor style nit.

Remove reference to softc from probe entirely...

Minor style cleanup. Get rid of extra {}, extra blank lines and some

o Fix style issues from de-Pification.
o change from _isa_ to _cbus_ to the largest extent possible to reflect that
this is really for cbus, not isa.
o Use ANSI function definitions.
o Use ed_clear_memory
o eliminate kvtop

Make the special hp versions match the general ones. Also use fixed

definitions in a couple places.

Make it possible to unload ed. Move the ed_pccard_detach routine to

Since I don't actually have any non-pccard ed hardware I can test
with, I've only tested with my pccards.

always treated as a simple ne2000, which would fail to get the
right NIC address.
o Lookup device again in the probe routine and probe based on the

# note: a lot of OEM entries are in the ed_pccard_products such that we can

This makes all of my DL100xx cards at least probe the ethernet address
correctly, which it wasn't doing before. I can't seem to locate my
AX88xxx based cards, so those haven't been tested, but they were
busted before the change so they can't be any worse now...

Repair probe messages a bit. Previously, we'd print the ethernet
address, and additional information. Then the printing of the
ethernet address was moved into ether_attach, and so we were printing
orphaned information about the card. Now the probe message is
prefixed by edX:. Prepare for it to move under bootverbose, but don't
move it there yet (the || 1 trick).

Add an option ED_NO_MIIBUS, which causes the `ed' driver to be

miibus support, so it's useful to be able to avoid the bloat of
all the mii devices for small fixed-purpose kernels.

Add a few missing spl calls in preparation for an MFC of the miibus
support.

Remove an old hack that remembered if the card type was Linksys by
storing a flag in the global variable 'linksys' during the probe
routine and reading it during the attach routine. We now have the
ED_VENDOR_LINKSYS vendor code stored in sc->vendor, so check that
instead.

Attach the miibus for Linksys/Dlink cards from the attach routine,
not from the probe routine. This was an oversight when I originally
ported the miibus support to -current, though it was mostly harmless.

We now set the vendor code to the new value ED_VENDOR_LINKSYS in
ed_pccard_Linksys() at probe time. Then ed_pccard_attach() checks
the vendor code, and sets up the miibus if appropriate.

Update the ed driver to probe and attach under a NEWCARD kernel (I was

Something isn't quite right.. when the driver allocates and activates
its resources, the IO space that was requested reads as all zeros (versus
the original 0xff's as it normally is when there is no device responding).

Also, deactivate the resources before releasing them. OLDCARD doesn't
seem to care but NEWCARD/CARDBUS get rather unhappy if you release
a resource that hasn't been deactivated yet.

Make pcic_p.c only compile with oldcard kernels.

Network modules are all "if_foo" not "foo". Avoid the confusing spew that

this if it's not defined. (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

Use COMPAT_PCI_DRIVER() for registration if it exists. This shouldn't
hurt the driver portability to 3.x too much for where drivers are shared.

Bring the 'new-bus' to the i386. This extensively changes the way the

not yet using the new resource manager. Once fully converted, all drivers
will be loadable, including PCI and ISA.

Sigh, kill setting of 0WS...it breaks more machines than it fixes.

The previous change added a use of the DATA_SET macro, but forgot

failed" message. Surprisingly, the missing include caused only
two compiler warnings. The compilation still "succeeded" anyway.

- Instead of relying on a functional call to register PCARD-capable drivers,
use a Linker Set. Note, if a driver is loaded as an LKM if will have
to use the function call, but since none of the existing drivers
are loadable, this made things cleaner and boot messages nicer.

- Functional changes to PCCARD support.
* Kill individual drivers 'suspend' routines, since there's no simple/safe
way to suspend/resume a card w/out going through the complete probe

* Default to using the apm_pccard_resume sysctl code, which basically
pretends the card was removed, and then re-inserted. Suspend/resume
is now 'emulated' with a fake insert/removal. (Hence we no longer
need the driver-specific suspend routines.)

Megacommit to straigthen out ETHER_ mess.

I'm pretty convinced after looking at this that the majority of our
drivers are confused about the in/exclusion of ETHER_CRC_LEN :-(

Replace about 60 lines of code with a call to ether_ioctl().
This can be done for most of our ethernet drivers.

Added #include of <machine/md_var.h>. This will be needed when
some declarations are moved from <machine/cpufunc.h> to better
places.

Removed unused #includes of <i386/isa/icu.h> and <i386/isa/icu.h>. icu.h
is only used by the icu support modules and by a few drivers that know
too much about the icu (most only use it to convert `n' to `IRQn'). isa.h
is only used by ioconf.c and by a few drivers that know too much about
isa addresses (a few have to, because config is deficient).

Clean up the warnings produced by the recent PCI code. Requested by
SE since he doesn't have good access right now

Add support for NE2000 compatible PCI Ethernet cards. The PCI probe
is enabled by having an "device ed0 at isa? [...]" config line.
The first PCI card will get a unit number one higher than the highest
defined for any ISA card of the ED type, e.g. if ed0 and ed1 are
configured, then the PCI cards will be ed2, ed3, ...

BEWARE: If you have configured your kernel as ed0 with the port address
as assigned by the PCI BIOS, then your card will be found by both the
PCI and ISA probes, and bad things may happen. Make sure to restore
the original port address form the GENERIC kernel for the ed0 device!

A mixed bag of changes, relating to getting the state in "lsdev" right,
and pccard support to work sensibly. Better by far, but still not good.

Say goodbye to IFF_NOTRAILERS. Support for trailers was officially
dropped for 4.4, but for some reason this flag lived on. (Until
today, that is.)

PCCARD support.

if_ze.c was derived from if_ed.c about 42 (!) versions ago. It is now
scheduled for demolition. This is a first step: get rid of if_zereg.h,
by adding the five extra definitions to if_edreg.h.
Also add some definitions which will become needed when if_ze.c gets
replaced entirely by pccard and if_ed.c. (this is a 2.1.0 candidate)

Remove extra arg from the call to ds_crc().

Fixed bug where a bogus packet length could cause a panic if the length
was less than sizeof(struct ed_ring).

Change memcmp() to bcmp(). memcmp() isn't declared or implemented
for the kernel, but gcc provides an inline version of it if the
kernel is compiled with -O.

Remove trailing whitespace.

After carefully reading three reference documents, and analyzing
the 802.3 frames generated by the DC21040 (which does automatic padding
of less-than-minimum frames) and the frames generated by the 'ed'
driver, I've found that there is indeed a bug in the size of "ETHER_MIN_LEN"
as reported by several people, John Hay being the most recent. The driver
was actually setting the length to 6+6+2+50 (64 bytes), which when adding
in the CRC (which is automatically appended to the frame and not included
in the length), the minimum frame is 4 bytes larger than it is supposed to
be. All of this is confirmed by tcpdump showing 50 bytes of data for
minimum frames from the 'ed' cards and 46 bytes from 'de' cards. This
analysis has also revealed that there is garbage in the un-filled in
portion at the end of the minimum frames from the 'ed' driver; I don't
plan to fix this.

Only use card's soft-configured irq if no irq was specified in the kernel
config file. This should fix a number of complaints regarding the auto
detection behavior.

Kill bogus duplicated code that resulted in an editing screwup of mine
that happend about 4 months ago.

Add a class field to devconf and mst drivers.
For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago). For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device. The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out. A few bytes saved by using
%b to format the features list rather than lots of ifs.

Add and move declarations to fix all of the warnings from `gcc -Wimplicit'
(except in netccitt, netiso and netns) and most of the warnings from
`gcc -Wnested-externs'. Fix all the bugs found. There were no serious
ones.

Much better fix/support for the 83c795 based cards (the new SMC EtherEZ)
by steve@simon.chi.il.us (Steven E. Piette). Minor changes by me.

Some fixes to device configuration, now that I've had a chance to do it
properly from the beginning:

1) The `kern_devconf' struct should be a part of the driver's
`softc' structure (now it is).
2) The `description' should say what the device actually is,
rather than just giving a model number (now it does).
3) The device should be registered even if the probe fails, so
that it can be reconfigured later.
4) For netifs, the device state should follow the IFF_UP flag.

Other network interfaces should follow this example. (Please?) Eventually
there should be a rundown routine doing the equivalent of setting IFF_UP
off, and perhaps more if warranted.

Made a few cosmetic changes, and fixed a bug in handling the case of the
remote DMA not completing correctly (the packet was still queued for xmit).

Possible fix for NE2000 problems...the remote byte count wasn't word
aligned even though the transfers are 16bit.

Get rid of unused variable.

Miscellaneous changes from Bill Paul:

- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
has only 8K of shared memory. The only way to have it properly detected
is to zero and test a few bytes of memory just about the first 8K region.
If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.

I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).

- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
the last column, like it should. You don't really notice this unless you
use certain programs that write all the way out to, say, the 80th column,
like VMSmail. Along with a one-line fix for this are some changes to
implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your
config file and give it a try. :)

Move ARP interface initialization into if_ether.c:arp_ifinit().

Always put received packets in an mbuf cluster. This simplifies the code
considerably and is measurably faster. Various comment fixes.

Moved conversion of ether_type to host byte order out of ethernet drivers
and into ether_input(). It was silly to have bpf want this one way and
ether_input want it another way. Ripped out trailer support from the few
remaining drivers that still had it.

Fixed rather serious bug where the interface wasn't started after it was
stopped in ed_setrcr(). I'm amazed that the driver worked at all. Thanks to
John Hay for pointing this out.

In cases where it is possible, use the card's configured irq rather than
the one compiled into the kernel. Left in some commented-out shared memory
performance test code.

Finished device configuration database work for all ISA devices (except `ze')
and all SCSI devices (except that it's not done quite the way I want). New
information added includes:

- A text description of the device
- A ``state''---unknown, unconfigured, idle, or busy
- A generic parent device (with support in the m.i. code)
- An interrupt mask type field (which will hopefully go away) so that
. ``doconfig'' can be written

This requires a new version of the `lsdev' program as well (next commit).

While I debugged this, I quenched the compile warnings from if_ed. no other
changes.

Add support for devconf to a large number of device drivers, and do
the right thing in dev_goawayall() when kdc_goaway is null.

isa_device.h: Added flag for sensitive HW. ed# seems to break if anything
else has been probed. This feature could go away again, if we can curb the
problem another way.

if_ed.c, syscons.c: Set the above flag. ed# because it needs it, syscons
because it looks stupid to "detect" the display you have already filled up
with text :-)

bt742a.c: Check bt_cmd() return-val during probe, thus failing on adaptec's.
Also silenced various printf's during the probe.

isa.c: Probe devices with the above flag set before the rest. Reduce the
number of "conflict" messages per device to one.

The code I wrote to write mbufs out using PIO had a bug in the handling
of mb_offset given the right sequence of 1 and 0 byte mbufs. This bug
was discovered by John Hood who also provided this fix - which is a
rewrite of the routine (and is easier to understand than the code I wrote).

Submitted by: John Hood <cgull@smoke.marlboro.vt.us>

Completely removed trailer support. The only reason I wrote that code in
the first place was so that BPF could grok trailer packets. I've since
decided that this is a job for tcpdump to decipher (if at all). Also
fixed up checks for received packet length to better cope with ancient
starlan boards.

Removed inclusion of pio.h and cpufunc.h (cpufunc.h is included from
systm.h). Merged functionality of pio.h into cpufunc.h. Cleaned up some
related code.

Removed MULTICAST ifdef's; it's no longer optional. Cleaned up code a
little.

Fixed minor typo in diagnostic message.

Fix up some sloppy coding practices:

- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.

Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles. This is not
quite complete yet, as `config' doesn't yet do the right thing. You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
make

Removed some unnecessary code that sets the link layer address. This should
be removed from the other drivers, too, as it is already done at a higher level
in the kernel.

Add delays after changing from 8/16 - 16/8 bit mode and after enabling/

While porting CAP to 386bsd/pk0.2.4 and now to FreeBSD Release 1.0
I found a couple of bugs associated with the packet filter. Here
are the fixes. I'm posting them here because they apply to
FreeBSD and 386bsd/pk0.2.4 and possibly to other *BSD.

The first occurs when using the packet filter to write raw
ethernet packets. The header consisting of the sender and
destination addresses and the protocol is removed and later
added back on, but with the byte order of the protocol reversed.
The fix ensures that the byte order in the protocol field is
swapped when it is removed.

The second fix ensures that SIOCGIFADDR works for BPF as claimed
in the man pages, by adding it to the ed driver. Similar fixes
will be needed for other ethernet drivers.

Make everything compile with -Wtraditional. Make it easier to distribute
a binary link-kit. Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.

NB: -Wtraditional will henceforth be forgotten. This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax. These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.

rewrote interrupt code to be cleaner, fixed up some other parts
to make it easier to add future board types.

As of this revision, all known bugs have been fixed. Some of the fixes include:

1) fixed 3c503 lock-up if the thinwire cable was disconnected at boot time
2) 8013EBT boards now work (quite well!) in 16bit/16k mode
3) ED_NO_DOUBLE_BUFFERING flag now works
4) slightly higer performance (about 3%) with 16bit WD/SMC boards
5) support for WD8013WC (10BaseT) boards

Additionally, the probe code has been reorganized to be much cleaner. This
revision of the driver is 1.25. The release notes have been updated as well.

* Fixed problem where some rev 8013EBT boards want the DCR_LS flag
* set in order to work in 16bit mode.

Seems also to improve performance by 15%! (?!) I think there might
be more to this flag than the manual says.

* Applied fixes from Bruce Evans to fix COW bugs, >1MB kernel loading,
profiling, and various protection checks that cause security holes
and system crashes.
* Changed min/max/bcmp/ffs/strlen to be static inline functions
- included from cpufunc.h in via systm.h. This change
improves performance in many parts of the kernel - up to 5% in the
networking layer alone. Note that this requires systm.h to be included
in any file that uses these functions otherwise it won't be able to
find them during the load.
* Fixed incorrect call to splx() in if_is.c
* Fixed bogus variable assignment to splx() in if_ed.c

* Added include of systm.h to pick up inlined min/max/bcmp if you have
* them in cpufunc.h. Modified wait loop in reset to look a little better.
* Added read for talley counters to prevent an infinite loop on old
* 8003E's if they (the counters) overflow.

Fixed logic problem which caused a bogus value to be written to the 3c503
asic register even if the board isn't a 3c503. This caused old 8003E's not
to work because they ignore IO address bits >10bits and the 3c503 asic is
located at +0x400....the offset was ignored by the 8003E and so the
value was written to one of the NIC registers. The bug was discovered by
Wolfgang Solfrank.

Added config file override for memory size and added flags to force
8bit or 16bit operation, and a flag to disable transmitter double buffering.
See the updated "ed.relnotes" file for information about how to set
the flags.
This should be considered the first "production" release. It still
needs a manual page, though.

Changed comment relating to memsize to be a little less misleading.

Fixed to allow iosiz config parameter to override what was (for me,
incorrectly) probed. This allows you more flexibility in getting weird
WD 80x3 clones to work.
