Now it does not have requirement to start up both station and AP interface simultaneously for WCN6855, this is to disable station and AP concurrency mode. After this patch, when station interface is up, then AP interface can not start up. AP interface can start up after station interface down. Also when AP interface is up, station interface can not start up. station interface can start up after AP interface down.
