From: Andrei Otcheretianski <andrei.otcheretianski@xxxxxxxxx> In order to imeplement the extended VI session feature for Miracast, the FW requires to detect the VI queue. The detection of the VI queue is done when it is assigned to a STA with ADD_STA command, so by this time the FW expects the queue to be already configured (mapped to VI AC and aggregation enabled). Previously, the queue configuration was done after STA modificaton which broke the extended VI session feature and resulted in higher latencies. Fix this by calling iwl_mvm_enable_agg_txq before station modification.
