o move tx taps from ath_start to ath_tx_start so lots more
state is available to tap
o add tx flags
o add tx rate
o add tx power (constant for the moment)
o add tx antenna state
a new bpf_mtap2 routine that does the right thing for an mbuf
and a variable-length chunk of data that should be prepended.
o while we're sweeping the drivers, use u_int32_t uniformly when
when prepending the address family (several places were assuming
sizeof(int) was 4)
o return M_ASSERTVALID to BPF_MTAP* now that all stack-allocated
mbufs have been eliminated; this may better be moved to the bpf
routines

For received packets, an status of NDIS_STATUS_RESOURCES means we need
to copy the packet data and return the ndis_packet to the driver immediatel.
NDIS_STATUS_SUCCESS means we get to hold onto the packet, but we have
to set the status to NDIS_STATUS_PENDING so the driver knows we're
going to hang onto it for a while.
For transmit packets, NDIS_STATUS_PENDING means the driver will
asynchronously return the packet to us via the ndis_txeof() routine,
and NDIS_STATUS_SUCCESS means the driver sent the frame, and NDIS
(i.e. the OS) retains ownership of the packet and can free it
right away.

ndis_init() will bring it up again, and we don't want it running

mbuf<->packet housekeeping. Instead, add a couple of extra fields
to the end of ndis_packet. These should be invisible to the Windows
driver module.
This also lets me get rid of a little bit of evil from ndis_ptom()

macro).

- When setting an ssid, program an empty ssid as a 1-byte string
with a single 0 byte. The Microsoft documentation says this is
how you're supposed to tell the NIC to attach to 'any' ssid.
- Keep trace of callout handles for timers externally from the
ndis_miniport_timer structs, and run through and clobber them
all after invoking the haltfunc just in case the driver left one
running. (We need to make sure all timers are cancelled on driver
unload.)
- Handle the 'cancelled' argument in ndis_cancel_timer() correctly.
supposed to be opaque to the driver, however it is exposed through
several macros which expect certain behavior. In my original
implementation, I used the mappedsystemva member of the structure
to hold a pointer to the buffer and bytecount to hold the length.
It turns out you must use the startva pointer to point to the
page containing the start of the buffer and set byteoffset to
the offset within the page where the buffer starts. So, for a buffer
with address 'baseva,' startva is baseva & ~(PAGE_SIZE -1) and
byteoffset is baseva & (PAGE_SIZE -1). We have to maintain this
convention everywhere that ndis_buffers are used.
Fortunately, Microsoft defines some macros for initializing and
manipulating NDIS_BUFFER structures in ntddk.h. I adapted some
of them for use here and used them where appropriate.
This fixes the discrepancy I observed between how RX'ed packet sizes
were being reported in the Broadcom wireless driver and the sample
ethernet drivers that I've tested. This should also help the
Intel Centrino wireless driver work.
Also try to properly initialize the 802.11 BSS and IBSS channels.
(Sadly, the channel value is meaningless since there's no way
in the existing NDIS API to get/set the channel, but this should
take care of any 'invalid channel (NULL)' messages printed on
the console.

- Add a bunch of net80211 support so that 802.11 cards can be twiddled
with ifconfig. This still needs more work and is not guaranteed to
work for everyone. It works on my 802.11b/g card anyway.
The problem here is Microsoft doesn't provide a good way to a) learn
all the rates that a card supports (if it has more than 8, you're
kinda hosed) and b) doesn't provide a good way to distinguish between
802.11b, 802.11b/g an 802.11a/b/g cards, so you sort of have to guess.
Setting the SSID and switching between infrastructure/adhoc modes
should work. WEP still needs to be implemented. I can't find any API
for getting/setting the channel other than the registry/sysctl keys.

Correct the recovery thread's loop so that it
will terminate properly on shutdown. We also
clear the recovery_thread proc pointer so that
any additional calls to aic_terminate_recovery_thread()
will not attempt to kill a thread that doesn't
exist. Lastly, code the loop so that termination
will still be successfull even if the termination
request occurs just prior to us entering the loop
or while the recovery thread is off recovering
commands.
that would cause an infinite loop any time we
manually flush the good status FIFO. Also make
our loop delay unconditional to ensure we don't
miss any FIFO allocations by the hardware.
