sends frames up the stack after changing the current channel then
the lookup by ieee channel number may fail leaving a null ptr in
se_chan; if this happens fallback to the channel recorded when the
frame is processed (curchan). Since the frame doesn't contribute
to scan results for the sta this is acceptable.

o do not override the home channel recorded for the sta when the frame is
received off-channel; this fixes a problem where we might think the sta
was operating on the channel the frame was received on causing association
requests to be ignored/rejected (likely cause of kern/99036)
o don't include rssi of off-channel frames in the avg rssi used to select
a bss; this gives us a better estimate of the signal we will see for the
station when on-channel

don't do this right; instead go to the scan cache so we pass through
auth state (if the cache is warm we can do this w/o an actual scan)

o add driver callback to handle notification of beacon changes;
this is required for devices that manage beacon frames themselves
(devices must override the default handler which does nothing)
o move beacon update-related flags from ieee80211com to the beacon
offsets storage (or handle however a driver wants)
o expand beacon offsets structure with members needed for 11h/dfs
and appie's
o change calling convention for ieee80211_beacon_alloc and
ieee80211_beacon_update
o add overlapping bss support for 11g; requires driver to pass
beacon frames from overlapping bss up to net80211 which is not
presently done by any driver
o move HT beacon contents update to a routine in the HT code area

- provide dummy routines for ic_scan_curchan and ic_scan_mindwell, we do not support those operations.
- add ieee80211_scan_done() to tell the scanning module that all channels have been scanned.
- pass IEEE80211_S_SCAN state off to net80211 so it can initiate scanning
- fix overflow in the rates array
- scale the rate value passed back from the firmware scan to the units that net80211 uses.

operating channel and use this in the scan cache rather than directly using
ic_curchan. Some firmware cards can only do a full scan and so ic_curchan does
not have the correct value.
Also add IEEE80211_CHAN2IEEE to directly dereference ic_ieee from the channel
to be used in the fast path.

through wpa_supplcant. If a sta is deauth'd (e.g. due to inactivity)
with roaming mode set to manual then a subsequent MLME assoc request
will be incorrectly handled and the station will never reauthenticate.
To fix this interpret a reason code of zero as sufficient to send an
auth request frame.
