86b47aaf36 Drop sched_scan filter if not enough match sets supported
Instead of including only a single SSID in the sched_scan request if
the driver does not support match sets, just drop the SSID filter and
configure more SSIDs up to the sched_scan limit.

with sched_scan driver commands. This will request offloading of

71093e5ea9 WPS: Include WSC IE in (Re)Association Response for maybe-WPS case
If the station is indicating use of WPS, WSC IE should be added into the
(Re)Association Response frame. This is clear for the case when WSC IE
was included in the (Re)Association Request frame. However, even the
WLAN_STA_MAYBE_WPS case may actually indicate use of WPS. Assume that to
be the case when WPA/WPA2 is enabled (i.e., when the STA does not
include WPA/RSN/WSC IE while AP has WPA/RSN enabled).

1323ee314e Move wpa_sm_remove_pmkid() call to PMKSA cache entry freeing
This makes it clearer that the PMKSA caching entry gets removed from
the driver regardless of how the internal entry from wpa_supplicant
gets cleared. In practice, this call was skipped only for the case
when the entry for the current AP was being updated, so the previous
version was likely to work with all drivers. Anyway, it is cleaner
to explicitly remove the old entry even in that case before the new
entry gets added.

ef992bbd3b wpa_gui-qt4: Improve scan results signal display
Display signal strength in dBm with visual indicator in the form of a
bar for scan results displayed by wpa_gui-qt4. Any signal > -35dBm is
treated as full signal bar, signals between range of -95<->-35dBm are
displayed linearly. Convert WEXT signal level value to scale that
nl80211 typically reports in dBm. The condition which differentiates
8-bit WEXT dBm and regular dBm is probably fragile, but there is
currently no way to know what the driver is going to report for signal
strength.
