6bf62dd1de o add noise floor to stats
o include current tx rate in stats so athstats gets a consistent
  snapshot and doesn't have to make an extra ioctl
o record tx rate for raw frames

d7736e139e Phantom beacon miss workaround: track the tsf of the last received
frame and if we get a beacon miss interrupt ignore it if we've received
a frame within the beacon miss interval.  This should never trigger
and the handling at the net80211 layer should likewise deal with this
but it doesn't hurt and can suppress extranous probe request frames.
Note that we can legtimately get a bmiss when under heavy load.

7b0c77eca9 Update monitoring support:
o record tsf in tx+rx frames
o switch from raw rssi to dbm for signal data and record both
  signal and noise floor data (hacked for now to assume a fixed
  noise floor; is correct with new hal)
o add monpass sysctl to control which rx'd frames are passed
  up with errors; especially useful to see frames with CRC errors
o mark 'd packets w/ a CRC error with radiotap's BADFCS flag

Also add placeholder code for calibrating the noise floor when
using newer hals.

eb2cdcb127 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

8cec0ab9a8 o track API change for HAL v0.9.6.1
o fix race condition when processing rx descriptors: because we use
  a self-linked descriptor at the end of the rx descriptor list to
  avoid rx overruns (which can easily happen for 5212 parts that enable
  PHY errors) we must carefully check that a descriptor is "done" by
  looking ahead to the next descriptor before believing the done bit
  in the current descriptor (this is all handled in the HAL since the
  rx descriptor format is chip-specific so we need to pass in two
  additional parameters--the physical address of the current descriptor
  and the virtual address of the next descriptor in the list)
o check copyout return status for SIOCGATHSTATS ioctl

73454c7385 Add support for the experimental radiotap capture format. With this
we no longer need the debugging code to dump packets.

d1d0cf62fe o pass control frames up the stack when in monitor mode (the 802.11 layer will
quietly discard them; this just permits them to be collected with bpf)
o add a counter for the number of rate control frames discarded when not in
  monitor mode
o move the rx "too short" statistic in the stat structure so non-error rx stats
  are together (NB: ABI change to apps that collect stats via driver ioctl)
