6a98e77848 o fix bug where rate wouldn't lift off lowest setting when operating as
an ap in 11g with protection enabled
o correct rate selection when operating in 11g with protection when no
  packets have been sent yet (from John Bicket)
o track api change to get first descriptor and use it to collect the frame
  length for calculating the state bin
o add more debugging and shuffle some existing debugging to give more info
o bump version to distinguish bug fixes

45dfb769f8 rev rate control api to pass the both the first+last tx descriptors
to the rate control module for tx complete processing; this enables
rate control algorithms to extract the packet length for xmits that
require multiple descriptors

fb92987525 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.

b6d4f1528e beacon handling fixups for adhoc mode:
o don't reclaim any previous beacon state in ath_beacon_alloc; do it
  explicitly in ath_newstate
o reference count the node held in the beacon frame state block
o process ibss merge more intelligently; let the state machine do the
  right thing instead of explicitly setting the new bssi id
o explicitly stop tx dma before doing beacon setup to handle the ibss
  merge case

341ffa612f 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

498543a7bd Correct beacon timer setup logic:
o lintval is in ms; must convert to TU's for passing to the hal
o roundup to calculate nexttbtt (should look at current tsf and pull the
  calculated nextbtt forward but this'll do for now)
o don't or- in HAL_BEACON_RESET_TSF when doing station timer setup; this
  is not needed and messes up the sleep timer calcs, though it's unclear
  if it mattered as the hal masks these values before use

c171b522d6 Like on the ath_rate_onoe component, make this compile on amd64. Convert
pointers to an integer via uintptr_t.

Fix an apparent bug that caused a compile failure.
ieee80211_iterate_nodes() takes ic->ic_sta as its first argument on the
onoe module.  It had just 'ic' here in the same context, which was a
mismatched argument.

adbd450602 Make this amd64-clean. sizeof is long on amd64, so things that do a printf
of a sizeof, need to use %z to get the correct type on all our platforms.
Also, convert integers<->pointers via uintptr_t.

(I think Sam's instructions were for me to commit this.  If I
 misunderstood, then I apologize in advance.)
