675ef586f0 mac80211: prevent tuning during scanning
Postpone calling ieee80211_hw_config if hardware scanning is active.
This is similar to solution for software scanning where channel setting
is delayed until scan complete.

fab7d4a2b1 mac80211: filter scan results on unusable channels
When you have an AP on channel 13, it will currently often enough
be listed in scan results even when the regulatory domain restricts
to channels 1-11. This is due to channel overlap. To avoid getting
very strange failures, don't show such APs in the scan results. The
failure mode will now go from "I can see the AP but not associate"
to "I can't see the AP although I know it's there" which is easier
to debug.

This problem was first really noticed by Jes Sorensen.

9ae4fda332 mac80211: allows driver to request a Phase 1 RX key
This patch makes mac80211 able to send a phase1 key for TKIP
decryption.
This is needed for drivers that don't do the rekeying by themselves

if decryption is ok, mac80211 calls to update_tkip_key  with a new
phase 1 RX key.

c49c3b77c8 libertas: convert GET_LOG to a direct command
Now uses __lbs_cmd() to get the "log" (it's actually more a snapshot of
various counters, not a sequential log). Besides the "mechanical" convertion
the patch add the following logical changes:

* Removes the priv->logmsg variable, it was only used in one place anyway,
  also don't blindly get the counters when associating. Getting the
  counters then the user asks via WEXT for them is good enought.
* don't set wstats.discard.fragment with log.rxfrag, because the latter is
  a counter for successfully received packets, not for fragmented packets.
