Revert previous commit and add myself to the list of people who should
know better than to commit with a cat in the area.

Add necessary include.

o Report ethernet status for at least 10BaseT media. Since I don't
have other media to test against, I've left that media reporting
unchanged.
o Enable the TX_PLL when we enable TX. This is harmless on most
cards, but required to get the 3c1 CF card working. Power savings
could be had by managing this better, but for now it gets my card
working.

Add newer commands

Start each of the license/copyright comments with /*-, minor shuffle of lines

MFP4:
o define EP_W2_ALT_EEPROM. we don't use it yet, but may soon.

Pass sc to GO_WINDOW macro.
Use SET_IRQ for pccard case, rather than exapnding it inline.

Requested by: mdodd

Minor style nits suggested by sam and mdodd:

o give an argument to EP_BUSY_WAIT
o use foo_locked rather than foo_body
o Add locking assertions for extra safety.

Whole grab-bag of changes:
o Make the driver MPSAFE
o Some changes due to diff reduction effort with vx.
o Removed some obsolete junk.

Transition to using bus_space macros rather than the inb/outb/etc.
Use EP_{READ,WRITE}{,_MULTI}_{1,2,4} instead. I've had several people
submit patches like this over the years of varying qualities, markm
being the last. The names were chosen in consulation with mdodd on
irc.

I've tested this with only PCMCIA cards: 3CCE589EC and 3CCSH572BT.
I've not tried with my more extensive ISA, EISA and cbus collection.

Style(9) cleanup. There was no consistent style in this driver, and
The next round of commits will be to fix up locking in it. This lot
is to at least give a consistent base to work off.

Properly detect ISA cards in EISA mode and skip them in the ISA identify
routine so that they will be picked up by the EISA front end.

PR: i386/2598

Speedup if_start routine a little. TX threshold logic needs some more
kicking but these changes get me around 1000 KB/sec.

Add defines for additional EEPROM locations and register definitions.

HEADS UP! All 3c5x9 users!

- Rip out all the static softc stuff and do softc allocation the right way.
- Rewrite most of the ISA code so that it provides a DEVICE_IDENTIFY
method to enumerate all non-PnP ISA devices.

This has the following consequences:

- No 'ep' devices may be hardwired.
- All hardwired devices will probably be detected twice.
By hardwired I mean:

device ep0 at isa? port 0x300 irq 10

- 'ep' devices are ordered by bus, slot, and then MAC address.

- Make 3c509B cards work in PnP mode. Yes, they really work.
- Convert over to using ifmedia for media selection. No more of this
lame 'linkX' stuff.
- Consolidate a lot of duplicated code.
- Make a stab at not breaking MII based PCCARD devices.
I doubt that the PCCARD stuff works any more than it did before my
changes but theres hope. My PCCARD hardware should arrive in a
week or so.
- Retreive the media settings from the card EEPROM rather than guessing.
I've got a 3c509-TPO that thinks its got an AUI port and if others
can report similar problems I'll write a bit of clever code that will
fix this but right now it works correctly on all but 1 card.
- Clean up a few things and make some cosmetic changes.
- Add myself as the MAINTAINER since nobody else wants to. I'm
in the best position to do this as I've got an example of most
of the cards:

EISA 3c579 bnc/aui
MCA 3c529 tp/aui
ISA 3c509 tpo
ISA-PnP 3c509B combo

If someone wants to send me a any cards I don't have I'd appriciate
it. Also welcome are 3c59x boards since I'll be folding if_vx and
if_ep at some point.

- Split out the ISA and PCCARD specific code.

- Split out the prototypes, externs and struct decls from if_epreg.h into
if_epvar.h.

- Add support for MCA based Etherlink III (3c529) devices.

None of this code is used right now; the old if_ep driver is still
in place and used.

I will eventually get around to converting if_ep_isa.c to newbus once I've
had a talk with Peter and DFR about the DEVICE_IDENTIFY() method.

I have tested this code on my PS/2. It works. I would like EISA and ISA
testers since my example hardware hasn't arrived yet.

Add:

dev/ep/if_ep.c optional ep
dev/ep/if_ep_isa.c optional ep isa
dev/ep/if_ep_eisa.c optional ep eisa
dev/ep/if_ep_mca.c optional ep mca
dev/ep/if_ep_pccard.c optional ep card

to sys/conf/files

Remove:

i386/eisa/3c5x9.c optional ep
i386/isa/if_ep.c optional ep

from sys/i386/conf/files.i386

PCCARD testers wanted!

I will switch off and cvs rm the old driver in favor of this copy once
I've had positive feedback or have the hardware to verify that it works.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Fixed pessimized (short) i/o port type.

The change in if_epreg.h affects if_epreg.o and 3c5x9.o.

These changes are probably harmless, but I can't test them.

Various cleanups for remanents of devconf.

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 :-(

Add interrupt register set up with original register value
before attaching. Without this fix, 3c579(EISA) never make
any H/W inturrupt.

At long last, we know have support for the 3C589 in a FreeBSD release
using the existing files using the existing PCCARD support. Now that
this is in place I would like to fixup the PCCARD hooks and remove the
if_zp driver. At this point, we support everything we used to support
*AND MORE* with the PCCARD code.

[ This works on both my 3C589B and 3C589C ]

Fix media type determination.

Clean up the 3c5x9 driver and add an eisaconf probe to it. This should
prevent it from conflicting with other drivers (like the aic7xxx driver).
Most of the work was in spliting out common portions of the driver and
making them generic enough to be called from the eisaconf probe.

Clean up Ethernet drivers:
- fill in and use ifp->if_softc
- use if_bpf rather than private cookie variables
- change bpf interface to take advantage of this
- call ether_ifattach() directly from Ethernet drivers
- delete kludge in if_attach() that did this indirectly

Fix a bunch of spelling errors in the comment fields of
a bunch of system include files.

Finally commit Serge's multicast and "misc other changes" patch. I
don't have a network to test it on here, but it does probe my card okay.

Andres Vega Garcia's improvements to the ep driver. This driver is a merging
of the 1.1.5 driver, a recent version of the NetBSD driver, Andres'
transmission start threshold code, and all other relavent changes to the driver
since it was brought into 2.0. The multicast support from NetBSD has not be
folded in yet. I've tested it under high loads for two weeks and it is now
robust enough to be included in the GENERIC kernel.

Update the if_ep driver for the 3C579 and bring over some of the
changes from the netbsd driver.
This is not complete: the detection of the irq in the eisa does not
work and sometimes the reset for the 3C509 in ISA in an EISA bus system
don't work ( Need a hard reset to be found again == reset knob).

First beta version of the 3C509 driver changed for FreeBSD. Known
problems in the moment are stray intr's in the ifconfig up/down.
No way to select all three interfaces on a combo card with
AUI/BNC/UTP interfaces and the performance doesn't look good.
Only tested with a ISA AUI/BNC card yet.

Committed the original NetBSD version of this driver to get the changes
made for FreeBSD as cvs diffs. This is the 3C509 ethernet driver.
