If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b95d08e1ffd9164fe8dfa2ec3f294374af136c02 Author: Sreeramya Soratkal <quic_ssramya@xxxxxxxxxxx> Date: Tue Mar 1 11:33:20 2022 +0530 nl80211: Update bss channel on channel switch for P2P_CLIENT [ Upstream commit e50b88c4f076242358b66ddb67482b96947438f2 ] The wdev channel information is updated post channel switch only for the station mode and not for the other modes. Due to this, the P2P client still points to the old value though it moved to the new channel when the channel change is induced from the P2P GO. Update the bss channel after CSA channel switch completion for P2P client interface as well.
