Add a new routine ieee80211_drain_ifq that does this and use it
instead of IF_DRAIN.

o add IEEE80211_F_JOIN flag to ieee80211_fix_rate to indicate a station
is joining a BSS; this is used to control whether or not we over-write
the basic rate bit in the calculated rate set
o fix ieee80211_fix_rate to honor IEEE80211_F_DODEL when IEEE80211_F_DONEGO
is not specified (e.g. when joining an ibss network)
o on sta join always delete unusable rates from the negotiated rate set,
this was being done only ibss networks but is also needed for 11g bss
with mixed stations
o on sta join delete unusable rates from the bss node's rate set, not the
scan table entry's rate set
o when calculating a rate set for new neighbors in an ibss caculate a
negotiated rate set so drivers are not presented with rates they should
not 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
particular this fixes use of wme in adhoc demo mode, it wasn't possible
to set the txop limit because the aggressive mode logic would override

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

device drivers to declare that the ifp->if_start() method implemented
by the driver requires Giant in order to operate correctly.
Add a 'struct task' to 'struct ifnet' that can be used to execute a
deferred ifp->if_start() in the event that if_start needs to be called
in a Giant-free environment. To do this, introduce if_start(), a
wrapper function for ifp->if_start(). If the interface can run MPSAFE,
it directly dispatches into the interface start routine. If it can't
run MPSAFE, we're running with debug.mpsafenet != 0, and Giant isn't
currently held, the task is queued to execute in a swi holding Giant
via if_start_deferred().
Modify if_handoff() to use if_start() instead of direct dispatch.
Modify 802.11 to use if_start() instead of direct dispatch.
This is intended to provide increased compatibility for non-MPSAFE
network device drivers in the presence of Giant-free operation via
asynchronous dispatch. However, this commit does not mark any network
interfaces as IFF_NEEDSGIANT.

This change paves the way for interface renaming and enhanced pseudo

EINPROGRESS return value to mean "don't do any of the normal work"
o correct active scanning so the first channel is only scanned once and so
per-channel passive mode is properly honored
o expose 802.11 FSM state names so every driver doesn't keep a private copy
o eliminate node parameter to ieee80211_begin_scan; it was not being used
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
almost all ifmedia actions
