Thanks, applied. Though, I left the NL80211_ATTR_MAC addition in place for now for the cases where MAC address randomization is not used so that wpa_supplicant remains compatible with older kernel versions that did not yet support NL80211_ATTR_BSSID.

With changes to optimize scan for specific BSSID, there arises a scenario where in nl80211_trigger_scan is called with a scan randomization enabled. A combination of NL80211_ATTR_MAC and scan randomization results in invalid error for the scan request. In order to fix the issue we use attribute NL80211_ATTR_BSSID instead of NL80211_ATTR_MAC.
