7e62e45f53 fixes a broken software beacon miss handler. There is a race to check
vap->iv_bmiss_count == 0 in ieee80211_swbmiss because iv_swbmiss_task is
enqueued by taskqueue.

39c3faaf70 o assert TDMA_MAXSLOTS is 2 so noone tries to blindly increase it
o add safety belt in vdetach for failed state block allocation
o fix dynamic change to tdma config; ERESTART may not result in
  kicking the state machine so we need to explicitly mark the
  beacon for update

5463c4a485 Overhaul monitor mode handling:
o replace DLT_IEEE802_11 support in net80211 with DLT_IEEE802_11_RADIO
  and remove explicit bpf support from wireless drivers; drivers now
  use ieee80211_radiotap_attach to setup shared data structures that
  hold the radiotap header for each packet tx/rx
o remove rx timestamp from the rx path; it was used only by the tdma support
  for debugging and was mostly useless due to it being 32-bits and mostly
  unavailable
o track DLT_IEEE80211_RADIO bpf attachments and maintain per-vap and
  per-com state when there are active taps
o track the number of monitor mode vaps
o use bpf tap and monitor mode vap state to decide when to collect radiotap
  state and dispatch frames; drivers no longer explicitly directly check
  bpf state or use bpf calls to tap frames
o handle radiotap state updates on channel change in net80211; drivers
  should not do this (unless they bypass net80211 which is almost always
  a mistake)
o update various drivers to be more consistent/correct in handling radiotap
o update ral to include TSF in radiotap'd frames
o add promisc mode callback to wi

9d90db9307 o move tdma+superg protocol defs out of public view
o add #ifdef _KERNEL to superg+tdma include files so they can be used
  by user code to get the protocol defs

2bc3ce7732 Minor cleanups of tdma protocol handling:
o break out version-related code to simplify rev'ing the protocol
o add parameter validation macros so checks that appear multiple places
  are consistent (and easy to change)
o add protocol version check when looking for a scan candidate
o improve scan debug output format
o rewrite beacon update handling to calculate a bitmask of changed values
  and pass that down through the driver callback so drivers can optimize work
o do slot bounds check before use when parsing received beacons

cc3e9fe79c change tdma slave behaviour: if the channel is locked don't do bmiss handling
(so no scanning/roaming)

6a76ae216e Add modes for 1/2 and 1/4-width channels so we have separate roaming
and xmit parameters.  This makes it possible to use tdma on fractional
channels.
o add IEEE80211_MODE_HALF and IEEE80211_MODE_QUARTER; note these are
  band-agnostic (may need revisiting)
o setup all default rates in ic_sup_rates instead of doing it only
  for active modes; we need these to calculate the default tx parameters
  which are not recalculated after a regulatory update (can't just
  recalculate after installing a new channel list because we might
  clobber user settings)
o remove special case code in ieee80211_get_suprates; this is now
  a candidate for an inline or removal
o add various entries for new modes (roaming+tx params, wme, rate
  mapping, scan set setup, country ie construction, tdma, basic rates)

Note these modes are intentionally not visible through if_media.

10ad9a77f3 TDMA support for long distance point-to-point links using ath devices:
o add net80211 support for a tdma vap that is built on top of the
  existing adhoc-demo support
o add tdma scheduling of frame transmission to the ath driver; it's
  conceivable other devices might be capable of this too in which case
  they can make use of the 802.11 protocol additions etc.
o add minor bits to user tools that need to know: ifconfig to setup and
  configure, new statistics in athstats, and new debug mask bits

While the architecture can support >2 slots in a TDMA BSS the current
design is intended (and tested) for only 2 slots.
