 * struct iwl_mld_txq - TX Queue data

 * @fw_id: the fw id of this txq. Only valid when &status.allocated is true.
 * @status: bitmap of the txq status
 * @status.allocated: Indicates that the queue was allocated.
 * @status.stop_full: Indicates that the queue is full and should stop TXing.
 * @list: list pointer, for &mld::txqs_to_add
 * @tx_request: makes sure that if there are multiple threads that want to tx
 *	from this txq, only one of them will do all the TXing.
 *	This is needed to avoid spinning the trans txq lock, which is expensive
