Log Message:
From FreeBSD.  Lots has changed.  I lazily yank text from the
FreeBSD commit log:

----------------------------
use correct malloc type to allocate struct ieee80211_node's

Noticed by:	phk
----------------------------
do proper subclassing of node free+copy; the previous hack falls apart when
the 802.11 layer does useful work

Obtained from:	madwifi
----------------------------
transmit beacon frames directly instead of defering them to a swi; there
was too much delay

Obtained from:	madwifi
----------------------------
update copyright notice for 2004
----------------------------
check more quickly (and directly) if an interrupt is pending; this reduces
work done in ath_intr when the irq is shared

Obtained from:	madwifi
----------------------------
cleanup descriptor allocation if attach fails

Obtained from:	madwifi
----------------------------
remove use IEEE80211_C_RCVMGT
----------------------------
radiotap updates:

o force little-endian byte order for header
o pad header to 32-bit boundary to guard against applications that assume
  packet data alignment
----------------------------
Don't announce MAC addresses twice.
(ieee80211_ifattach() calls ether_ifattach().)
----------------------------
Make this compile on amd64.

"I'll cope" by:  sam
----------------------------
When draining the tx queue reclaim any node references held in packets.
This fixes a problem when operating as an AP where clients would get
stuck in the node table because the reference count never went to zero.
----------------------------
When ath_hal_stoptxdma returns an error dma is still likely stopped
so don't just stop trying to send a beacon frame or we'll be more likely
to lose sync.  This only seems to happen on some older chips.
----------------------------
use ath_reset instead of ath_init when recovering from a watchdog timeout:
resetting the hardware is sufficient, no need to reset the 802.11 fsm
----------------------------
make hw.ath.debug a tunable
----------------------------
make hw.ath.outdoor and hw.ath.countrycode tunables
----------------------------
split debugging messages up into classes;
ah_debug is now treated as a bit vector
----------------------------
update radiotap support to reflect recent changes:

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
----------------------------
o eliminate widespread on-stack mbuf use for bpf by introducing
  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
