In current code, when STA/P2P Client connect to AP/P2P GO, the WMI command sequence is: peer_create->vdev_start->vdev_up And sequence of STA/P2P Client disconnect from AP/P2P GO is: peer_delete->vdev_down->vdev_stop This sequence of disconnect is not opposite of connect. For STA or P2P GO, bss peer is not needed by firmware during handling vdev stop command. So with this sequence, STA and P2P GO can work normally. But for P2P Client, firmware needs bss peer in some functions during handling vdev stop command. The opposite sequence of disconnect should be: vdev_down->vdev_stop->peer_delete So change the sequence of disconnect as above opposite sequence for WCN7850.
