Merge tag 'wireless-drivers-next-2020-05-30' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Kalle Valo says: ==================== wireless-drivers-next patches for v5.8 Third set of patches for v5.8. Final new features before the merge window (most likely) opens, noteworthy here is adding WPA3 support to old drivers rt2800, b43 and b43_legacy. Major changes: ath10k * SDIO and SNOC busses are not experimental anymore ath9k * allow receive of broadcast Action frames ath9k_htc * allow receive of broadcast Action frames rt2800 * enable WPA3 support out of box b43 * enable WPA3 support b43_legacy * enable WPA3 support mwifiex * advertise max number of clients to user space mt76 * mt7663: add remain-on-channel support * mt7915: add spatial reuse support * add support for mt7611n hardware iwlwifi * add ACPI DSM support * support enabling 5.2GHz bands in Indonesia via ACPI * bump FW API version to 56 ==================== Signed-off-by: David S.

+ * @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

+ *
+ * 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.

- * @q: generic Rx/Tx queue descriptor
- * @tfds: transmit frame descriptors (DMA memory)
- * @first_tb_bufs: start of command headers, including scratch buffers, for
- *	the writeback -- this is DMA memory and an array holding one buffer
- *	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
- * @stuck_timer: timer that fires if queue gets stuck
- * @trans_pcie: pointer back to transport (for timer)
- * @need_update: indicates need to update read/write index
- * @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
- * @bc_tbl: byte count table of the queue (relevant only for gen2 transport)
- * @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
- *
- * 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.
