From: Arik Nemtsov <arik@xxxxxxxxxx> When TDLS peers are present the FW will send packets on a dedicated TID vs. the peer when performing TDLS channel-switches. The driver configures the TID on connection to the peer and the FW is responsible for maintaining the state of QoS seqno and PN/IV for encryption. If the FW asserts, the driver cannot correctly reconfigure the starting seqno/PN to the reloaded FW, thus forcing us to reconnect the peer.
