From: Andrei Otcheretianski <andrei.otcheretianski@xxxxxxxxx> Queued frames aren't processed during scan, which results in an inability to complete the BA session establishment until the scan ends. Since we can't tx frames until the BA agreement setup is complete, it might result in a very large latency during scan. Fix this by allowing to process queued skbs while scanning in HW. This should be ok since the devices which support hw scan should be able to handle tx/rx while scanning. During SW scan, mac80211 drops any txed frames besides probes and NDPs, so it is still needed to delay processing of the queued frames till the SW scan is done.
