* for each command on the queue
* @ first_tb_dma : DMA address for the first_tb_bufs start
* @ entries : transmit entries ( driver state )
* @ lock : queue lock
* @ reclaim_lock : reclaim lock
* @ stuck_timer : timer that fires if queue gets stuck
* @ trans : pointer back to transport ( for timer )
* @ ampdu : true if this queue is an ampdu queue for an specific RA / TID
* @ wd_timeout : queue watchdog timeout ( jiffies ) - per queue
* @ frozen : tx stuck queue timer is frozen
* @ frozen_expiry_remainder : remember how long until the timer fires
* @ block : queue is blocked
* @ bc_tbl : byte count table java.lang.StringIndexOutOfBoundsException: Index 30 out of bounds for length 0
* @ write_ptr : 1 - st empty entry ( index ) host_w
* @ read_ptr : last used entry ( index ) host_r
* @ dma_addr : physical addr for BD ' s
* @ n_window : safe queue window
* @ id : queue id
* @ low_mark : low watermark , resume queue if free space more than this
* @ high_mark : high watermark , stop queue if free space less than this
* @ overflow_q : overflow queue for handling frames that didn ' t fit on HW queue
* @ overflow_tx : need to transmit from overflow
*
* A Tx queue consists of circular buffer of BDs ( a . k . a . TFDs , transmit frame
* descriptors ) and required locking structures .
*
* Note the difference between TFD_QUEUE_SIZE_MAX and n_window : the hardware
* always assumes 256 descriptors , so TFD_QUEUE_SIZE_MAX is always 256 ( unless
* there might be HW changes in the future ) . For the normal TX
* queues , n_window , which is the size of the software queue data
* is also 256 ; however , for the command queue , n_window is only
* 32 since we don ' t need so many commands pending . Since the HW
* still uses 256 BDs for DMA though , TFD_QUEUE_SIZE_MAX stays 256 .
* This means that we end up with the following :
* HW entries : | 0 | . . . | N * 32 | . . . | N * 32 + 31 | . . . | 255 |
* SW entries : | 0 | . . . | 31 |
* where N is a number between 0 and 7 . This means that the SW
* data is a window overlayed over the HW queue .
