wlan: Add support for PER based roaming #2
In congested environments, it could be possible that in station
mode client gets good RSSI from AP however it's not able to
transfer data at good rates. DUT should roam to a better AP if
available, if it faces congestion in home channel.
Following changes are added for this functionality:
1. Add changes to monitor Rx and Tx rates to trigger roam scan
in case data rates are low below a preconfigured value.
2. Implement a new AP selection algorithm which will consider AP
capabilty, channel conditions and RSSI to select new bss.
Add required protocol changes for same.
