Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Create a generic PCCARD_PNP_INFO from the MODULE_PNP_INFO building
block. Use it in all the PNP drivers to export either the current PNP
table. For uart, create a custom table and export it using
MODULE_PNP_INFO since it's the only one that matches on function
number.

Replay r286410. Change KPI of how device drivers that provide wireless
connectivity interact with the net80211 stack.

Historical background: originally wireless devices created an interface,
just like Ethernet devices do. Name of an interface matched the name of
the driver that created. Later, wlan(4) layer was introduced, and the
wlanX interfaces become the actual interface, leaving original ones as
"a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer
and a driver became a mix of methods that pass a pointer to struct ifnet
as identifier and methods that pass pointer to struct ieee80211com. From
user point of view, the parent interface just hangs on in the ifconfig
list, and user can't do anything useful with it.

Now, the struct ifnet goes away. The struct ieee80211com is the only
KPI between a device driver and net80211. Details:

- The struct ieee80211com is embedded into drivers softc.
- Packets are sent via new ic_transmit method, which is very much like
the previous if_transmit.
- Bringing parent up/down is done via new ic_parent method, which notifies
driver about any changes: number of wlan(4) interfaces, number of them
in promisc or allmulti state.
- Device specific ioctls (if any) are received on new ic_ioctl method.
- Packets/errors accounting are done by the stack. In certain cases, when
driver experiences errors and can not attribute them to any specific
interface, driver updates ic_oerrors or ic_ierrors counters.

Details on interface configuration with new world order:
- A sequence of commands needed to bring up wireless DOESN"T change.
- /etc/rc.conf parameters DON'T change.
- List of devices that can be used to create wlan(4) interfaces is
now provided by net.wlan.devices sysctl.

Most drivers in this change were converted by me, except of wpi(4),
that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing
changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann,
Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in
testing.

Still, drivers: ndis, wtap, mwl, ipw, bwn, wi, upgt, uath were not
tested. Changes to mwl, ipw, bwn, wi, upgt are trivial and chances
of problems are low. The wtap wasn't compilable even before this change.
But the ndis driver is complex, and it is likely to be broken with this
commit. Help with testing and debugging it is appreciated.

The two PLANEX cards listed in pccarddevs, identified only by their
CIS, weren't actually used anywhere (other than the generic PC Card
code when certain variables are defined). They aren't used in NetBSD
either. Make things simpler by removing them. Change PLANEX_2 to
PLANEX and tweak wi and owi to use that instead. The PLANEX id seems
to actually be pci ID assigned to planex, not its pcmcia id. Ooops.
I don't know if this is a reporting error from where this entry came
from, or if it is a mistake on PLANEX's part. I suspect the latter,
as ACTIONTEC and NEWMEDIA made the same mistake (although new media
may be because it uses an advansys chip inside). Make a note of this
in the file. The 0xc entires may be JEITA assigned, so note that as
well.

# This leaves just 3 entries that are totally unknown: airvast, archos
# and edimax although the arivast number is the same assigned to
# avertec in usb...

Use Intersil chip names for the symbols, since many makers use the
intersil IDs but their own name in the CIS.

Only match cards that claim to be network cards. I've had two
different cards that matched vendor/id, but weren't wi cards. This is
because the vendor foolishly didn't have unique product ids. Symbol

example...

Fix disordering of pccarddevs.h noticed by bde. Also remove a few
redundant includes and fix some of the include disordering.

Submitted by: bde

Move to generating pccarddevs.h on the fly, both for the kernel and
the modules.

Also generate usbdevs.h automatically now, but a non-kernel file is
stopping that at the moment.

It turns out that the module dependency on pccard is in error. Since
there's not dependencies on pccard symboles, such a dependency is not
necessary. This means that drivers that have multiple attachments can
not drag bogus devices into the kernel at load time.

We can't (yet) do this with pci and isa. Drivers written for them
actually do seem to have symbols that depend on these busses'
implementation code.

ndis not touched until other things can be tested.

- Express hard dependencies on bus (pci, isa, pccard) and
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)

Make sure that pp_name is non-null before setting the device
description. This allows us to rely entirely on the CIS entries if
necessary...

Back out the _ND change. I plan on making all drivers default to that with
a special _DESC version for those cards whose CIS is insufficient for some
reason. This should save about 3k of kernel strings when complete.

Use the new _ND macros to not include the description strings. If any
of the entries have a description, we'll use that to override the
description that the pccard layer generates for us.

This saves about 930 bytes in the module, so I feel it won't hurt the
crowded boot disks....

# other modules to follow

Don't set the decription, since the pccard layer does that for us now.
Remove the duplicate entries that were there to disambiguate different
cards that were the same, yet people wanted to have different dmesg.

Add code that will download firmware to a Symbol LA4100-series of CF

a kernel option (WI_SYMBOL_FIRMWARE).

Note: This only downloads into the RAM of these cards. It doesn't
download into FLASH, and is somewhat limited. There needs to be a
better way to deal, but this works for now. My Symbol LA4132 CF card
works now.

Add ActionTec HWC01170 and Linksys IWN2

Integrate the hostap stuff that Thomas Skibo <skibo@packbell.net>
wrote. This code was for 4.5-release, so I've ported it to -current
and made a few minor tweaks. The biggest non-style tweak was to not
make access point the default.

More changes will be needed to get this actually working, but I wanted
to get a relatively pure baseline. This doesn't seem to break what
works now.

The 3Com 3CRWE62092A (the XJack antenna product) does not have a host
interface that is compatible with the LUCENT or HERMES firmware.
Instead, it is like the various No Wires Necessary products that were
produced a while ago and then sold to intersil. It will require a
different driver altogether. Remove it from the list of supported
cards.

The 3CRWE777A apperas to be a re-badged SMC 2602W card, so the driver
appears to support it. Add it to the list.

Thanks to Todd Miller for loaning me the card during tonight's FRUUG
meeting for testing against CU's wireless infrastructure.

It would appear, from preliminary indications, that No Wires Necessary
cards aren't compatible with either Lucent or Intersil firmware.

Add some devices from OpenBSD/NetBSD:

o 3Com 3crwe62092a
o Addtron awp100
o No Wires Necessary WLAN 550 and 1148
o Proxim RANGELANDS 8340
