* @send_cmd:send a host command
* @send_cmd_pdu:send a host command: flags can be CMD_*
- * @get_tx_cmd: returns a pointer to a new Tx cmd for the upper layer use
* @tx: send an skb
- * @txq_agg_setup: setup a tx queue for AMPDU - will be called once the HW is
+ * @reclaim: free packet until ssn. Returns a list of freed packets.
+ * @tx_agg_alloc: allocate resources for a TX BA session
+ * @tx_agg_setup: setup a tx queue for AMPDU - will be called once the HW is

+ * @tx_agg_disable: de-configure a Tx queue to send AMPDUs

- * the ISR / tasklet etc... have finished running and the transport
- * layer shall not pass any Rx.
* @free: release all the ressource for the transport layer itself such as
* irq, tasklet etc...
+ * @stop_queue: stop a specific queue
+ * @check_stuck_queue: check if a specific queue is stuck
+ * @wait_tx_queue_empty: wait until all tx queues are empty
+ * @dbgfs_register: add the dbgfs files under this directory. Files will be
