o purge ath_initkeytable; it's not needed
o add multicast key search support for supporting multiple group keys
  (disabled for now; requires updated hal)
o create keycache entry for stations using open auth so they get h/w
  antenna management support

d3be6f5b0c Fixup radiotap handling of FCS and QoS frames per discussion with David Young:
o mark rx frames including FCS in the payload with the
  IEEE80211_RADIOTAP_F_FCS flag
o remove hack to copy 802.11 headers with padding out of line; instead mark
  the frames with IEEE80211_RADIOTAP_F_DATAPAD and require applications to
  do the work
o split precalculated radiotap flags into tx+rx now that they can be different

Note the full usefulness of these changes depends on updates to applications
that process radiotap data.

16b4851a16 Radiotap fixups:
o catch one place where we were not using ath_chan_change to
  switch channels; this fixes a problem where the channel
  settings were not being correctly reported in captured packets
o return unique channel identification in the channel flags;
  ethereal gets confused if you return merged flags (e.g. ofdm,
  cck, and 2Ghz) (this is workaround and should be removed if
  we can ever cleanup radiotap consumers)
o correct short/long preamble flag state for rx and treat tx
  the same--use a new hwflags array that gives us the data
  based on the h/w rate index/cookie
o add gross hack to handle radiotap capture of frames that
  come in with hardware padding; should be replaced by a
  flag in the radiotap header and more smarts in the apps
  that decode radiotap data

o fix race condition when processing rx descriptors: because we use

  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

to the 802.11 layer if they are at least IEEE80211_MIN_LEN
o mask off interrupt status bits that we don't care about so we don't do
  the wrong thing; this fixes a problem where the beacon miss interrupt status
  bit is delivered together with other status bits when operating in monitor
  mode (we would post a beacon miss swi and then do the wrong thing)

3065b96e25 must also check for 5Ghz channels when marking short preamble capability in
the beacon frames

f6aa038bbe o mark the device capable of short preamble (meaningless for the 5210 but
safe since the 802.11 layer does the right thing for 11a operation)
o select short preamble operation based on the negotiated capabilities; not
  just the local state/capability
o fillin the duration field in the 802.11 header as appropriate
o remove detection of 11g support; no longer needed

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

f07a6d989f Explicitly enable probe request frame reception when not in station mode;
this is needed for the 5212 which a separate filter bit for these frames.
