6124e858fd wpa_supplicant: Allow vifs to scan only current channel
If a VIF is already associated, then only scan on the associated
frequency if user requests such. This is a big help when using
lots of virtual stations.

f11b72c3e9 TDLS: Move AID=1 workaround into driver_nl80211.c
The use of AID=1 for the nl80211 dummy STA case is specific to the

55a2df4389 HS 2.0: Include HS 2.0 Indication element only for HS 2.0 association
The Hotspot 2.0 specification seems to mandate this element to be
included in all (Re)Association Request frames if the station is Hotspot
2.0 capable. However, that results in conflicts with other requirements
like no TKIP use when this element is present. The design is really
supposed to include the indication element only for Hotspot 2.0
associations regardless of what the current specification implies.
Remove the HS 2.0 Indication element from (Re)Association Request frame
whenever the connection is not for Hotspot 2.0 purposes.

There may be cases where multiple BSS entries for a single BSSID are in

when storing GAS/ANQP response.
