11df4239a6 change ieee80211_mhz2ieee to use the PSB mapping when the frequency
falls in the proper place, not when we're handed a 1/2 or 1/4-rate channel

ca4ac7ae14 Add initial support for 900MHz cards like the Ubiquiti SR9:
o add channel flag to enable freq <-> ieee channel # mapping (can
  go away in the future when ieee number is precomputed)
o add mapping between 900mhz freq's and channel #'s that gives a
  unique channel # for each half/quarter/full width channel
o remove assumptions that half/quarter rate channels on happen in 11a
o remove assumptions that all 11g channels are full width
o ensure ic_curchan is reset on mode change so changing the channel
  list (e.g. on countrycode change) doesn't leave curchan set to an
  invalid channel

There is still an issue with switching rate sets; to be fixed separately.

45fa8b0e9a o unbreak rate set defaulting
o mark 11g mode support on finding 11g or pure 11g (OFDM-only)
  channels; was requiring pure 11g which caused some contortions
  in drivers that manually setup their channel lists

41b3c790eb First cut at half/quarter-rate 11a channel support (e.g. for use
in the Public Safety Band):
o add channel flags to identify half/quarter-rate operation
o add rate sets (need to check spec on 4Mb/s in 1/4 rate)
o add if_media definitions for new rates
o split net80211 channel setup out into ieee80211_chan_init
o fixup ieee80211_mhz2ieee and ieee80211_ieee2mhz to understand half/quarter
  rate channels: note we temporarily use a nonstandard/hack numbering that
  avoids overlap with 2.4G channels because we don't (yet) have enough
  state to identify and/or map overlapping channel sets
o fixup ieee80211_ifmedia_init so it can be called post attach and will
  recalculate the channel list and associated state; this enables changing
  channel-related state like the regulatory domain after attach (will be
  needed for 802.11d support too)
o add ieee80211_get_suprates to return a reference to the supported rate
  set for a given channel
o add 3, 4.5, and 27 MB/s tx rates to rate <-> media conversion routines
o const-poison channel arg to ieee80211_chan2mode

aadecb1ac8 Default the rate sets for 802.11 operating modes so drivers aren't
required to.  Note this only happens when drivers don't set them
up before calling ieee80211_ifattach so this change is backwards
compatible.

9cab5ba3f9 back out public safety-specific channel number mapping; we can't do
it until we know it should be applied as otherwise we can map 11a
channels into the 2.4G range and choose the wrong item from the
chanenl array

97bcffbd74 o make driver override of net80211 parameter state consistent
with methods: instead of honoring non-zero values expect drivers
  to write their own values on return from ieee80211_ifattach

399178c917 correct checking for turbo channels: rev 1.24 fixed static turbo channels
but broke handling of the turboG channel; since we aren't ready to revamp
the channel list just check for turboA channels for now so channel 6 is
considered in auto mode

6f322b78de Update ieee80211_mhz2ieee to understand public safety bands and spectrum
that can potentially be mapped to negative ieee #'s.

NB: before operation on the latter can be supported we need to cleanup
    various code that assumes ieee channel #'s are >= 0

b5c9941514 Clarify/fix handling of the current channel:
o add ic_curchan and use it uniformly for specifying the current
  channel instead of overloading ic->ic_bss->ni_chan (or in some
  drivers ic_ibss_chan)
o add ieee80211_scanparams structure to encapsulate scanning-related
  state captured for rx frames
o move rx beacon+probe response frame handling into separate routines
o change beacon+probe response handling to treat the scan table
  more like a scan cache--look for an existing entry before adding
  a new one; this combined with ic_curchan use corrects handling of
  stations that were previously found at a different channel
o move adhoc neighbor discovery by beacon+probe response frames to
  a new ieee80211_add_neighbor routine

d365f9c760 Cleanup beacon/listen interval handling:
o separate configured beacon interval from listen interval; this
  avoids potential use of one value for the other (e.g. setting
  powersavesleep to 0 clobbers the beacon interval used in hostap
  or ibss mode)
o bounds check the beacon interval received in probe response and
  beacon frames and drop frames with bogus settings; not clear
  if we should instead clamp the value as any alteration would
  result in mismatched sta+ap configuration and probably be more
  confusing (don't want to log to the console but perhaps ok with
  rate limiting)
o while here up max beacon interval to reflect WiFi standard

o code reorg (relative to old netbsd-derived code) for future growth
o drivers now specify available channels and rates and 802.11 layer handles

o multi-mode support for 11a/b/g devices
o 11g protocol additions (incomplete)
o new element id additions (for other than 11g)
o node/station table redone for proper locking and to eliminate driver
  incestuousness
o split device flags and capabilities to reduce confusion and provide room
  for expansion
o incomplete power management infrastructure (need to revisit)
o incomplete hooks for software retry
o more...
