In the case of the ap_csa_disable test, I frequently see
failures due to the kernel *not* having switched, but the
CSA-STARTED event having been processed, and thus the
frequency having been updated already.
This is wrong at least for AP mode, the frequency we store
for this case internally in nl80211 should only be updated
when the channel switch completes, otherwise we end up in
a situation where the switch is aborted and the kernel is
thus on the old channel, but the internal information has
been updated and every subsequent mgmt-frame TX fails due
to being tagged with the wrong channel.

On a connect nl80211 event, wpa_supplicant uses
wpa_driver_nl80211_get_ssid() to fetch the current associated SSID to
compare to existing configurations. However,
wpa_driver_nl80211_get_ssid() uses drv->ssid, which is a cached value.
It is set when we explicitly initial a connect request using
wpa_supplicant. If the association was initiated outside of
wpa_supplicant, we need another way to populate drv->ssid. This commit
sets drv->ssid based on cfg80211 BSS information on connect/associate

conditional on drv->last_scan_cmd being NL80211_CMD_TRIGGER_SCAN. This
missed the part about the possibility of last_scan_cmd == 0 and an
externally started cfg80211 scan is ending. This could leave
drv->scan_state into SCAN_STARTED state even after the scan was

Fix this by updating drv->scan_state also in drv->last_scan_cmd == 0

The de-authentication flow in wpa_driver_nl80211_deauthenticate() can
result in a locally generated de-authentication event. To avoid getting

cleared when the next local deauth event is received. However, it is not
cleared when the event shows up after the wpa_supplicant has started a
