Currently ath11k support both station/AP mode for WCN6855, and it is configured with single_pdev_only, it means it has only one ath11k and one ieee80211_hw which registered in mac80211 and one wiphy registered in cfg80211. 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.
