a LinkSys card here in the office where reading the station address
fails the first time, but works find afterwards. Without this, the
probe fails. I don't think this will negatively impact any existing
cards, but I want to confirm this before MFC'ing.

Some style changes, add some braces, mostly residual from having
a lot of debug hooks added while working on this driver.
Bring in a plethora of changes from NetBSD:

revision 1.41

Fix wi_intr() to avoid touching card registers during insert/remove events,
when sharing an interrupt with other devices:
check sc->sc_enabled, and drop the interrupt if its' off.
revision 1.30
date: 2000/08/18 04:11:48; author: jhawk; state: Exp; lines: +4 -4
Copy wi_{dst,src}_addr from struct wi_frame into faked-up ether_header
instead of addr1 and addr2. THis means that tcpdump -e will show the
correct MAC address for communications with access points instead of showing
the BSSID.
In the future there should be 802.11 support for bpf/libpcap/tcpdump,
but that is aways down the road.
o Change the number of init tries from 5 to a #define.
o Allow up to 5s rather than 2s for commands to complete. This
is still much less than 51 minutes, but makes my intel card init
with more reliability than before.
Don't leak iospace when irq allocation fails. (call wi_free())
Call bus_release_resource() with the correct "rid" obtained from
bus_alloc_resource() that's saved in the softc instead of a hardcoded
0.
It appears that some of the new PRISM2 cards need it.
Fail the probe if we fail to read the MAC address.
Fix a comment.
Delete the unload printf. The bus system now prints this message.
a #defined constant, wrap a few long lines, etc... Also remove stupid
'all your base are belong to us' joke from comment that I don't really
care to see immortalized in the source tree.
All calls to mtx_init() for mutexes that recurse must now include
the MTX_RECURSE bit in the flag argument variable. This change is in
preparation for an upcoming (further) mutex API cleanup.
The witness code will call panic() if a lock is found to recurse but
the MTX_RECURSE bit was not set during the lock's initialization.
The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to
MTX_RECURSED, which is more appropriate given its meaning.
The following locks have been made "recursive," thus far:
eventhandler, Giant, callout, sched_lock, possibly some others declared
in the architecture-specific code, all of the network card driver locks
in pci/, as well as some other locks in dev/ stuff that I've found to
be recursive.

Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.
The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.
The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.

pseudo-IBSS mode). This is apparently necessary in order to obtain the
true MAC address of the sending station which is needed for PPPoE.

prevent a page fault if the card is ejected while BPF is in use. This
could happen if DHCP or tcpdump was in use on that interface during
ejection. Other drivers may also require this modification.

Also update wicontrol to enable/disable encryption, set WEP keys and set the
TX key index. Silver cards only have 40-bit keys. This is something of a quick
hack, but it works well enough for me to commit this from the LinuxWorld
exhibit floor.
The WEP support only shows up if you have a card that supports it.

- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing
the initial work here. One thing I changed was to have the attach
and detach routines work like the PCI drivers, which means that in
theory you should be able to load and unload the driver like the PCI
NIC drivers, however the pccard support for this hasn't settled down
yet so it doesn't quite work. Once the pccard work is done, I'll have
to revisit this.
- Add device wi0 to PCCARD. If we're lucky, people should be able to
install via their WaveLAN cards now.
- Add support for signal strength caching. The wicontrol utility has
also been updated to allow zeroing and displaying the signal strength
cache.
- Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko.
Currently this module is only built for the i386 platform, though once
the pccard stuff is done it should be able to work on the alpha too.
(Theoretically you should be able to plug one of the WaveLAN/IEEE ISA
cards into an alpha with an ISA slot, but we'll see how that turns out.
- Update LINT to use only device wi0. There is no true ISA version of
the WaveLAN/IEEE so we'll never use an ISA attachment.
- Update files.i386 so that if_wi is dependent on card.

reading from the NIC's internal buffers). Anything too large to fit
safely into an mbuf cluster buffer is discarded and an error logged.
I have not observed this problem with my own cards, but on user has
reported it and adding the sanity test seems reasonable in any case.

- Mention turbo adapters in the wicontrol.8 man page and provide a

WaveLAN's radio modem. The default is whatever the NIC uses since NICs
sold in different countries may default to different frequencies. (The
Lose95/LoseNT software doesn't let you select the channel so it's probably
not really meant to be changed.)
