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.

f818612b1b 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

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

a6c992f43c 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

6891c875c2 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.)

stuck in the node table because the reference count never went to zero.

a9c0425768 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.

437ffe1823 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

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

85643802a4 Don't count PHY errors as input errors. This is important for
5212-based devices because PHY errors are used to collect data
on environmental noise that and doesn't truly reflect the state
of the communications media.  The result is confused users.
Folks that want to watch PHY errors can still get the statistics
through the device ioctl (used by athstats).

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.
