14 * struct iwl_mld_txq - TX Queue data
15 *
16 * @fw_id: the fw id of this txq. Only valid when &status.allocated is true.
17 * @status: bitmap of the txq status
18 * @status.allocated: Indicates that the queue was allocated.
19 * @status.stop_full: Indicates that the queue is full and should stop TXing.
20 * @list: list pointer, for &mld::txqs_to_add
21 * @tx_request: makes sure that if there are multiple threads that want to tx
22 *	from this txq, only one of them will do all the TXing.
23 *	This is needed to avoid spinning the trans txq lock, which is expensive
