2020-09-24mt76: Use fallthrough pseudo-keywordGustavo A. R. Silva
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2020-09-24mt76: convert from tx tasklet to tx worker threadFelix Fietkau
This improves performance by allowing the scheduler to move the tx scheduling work to idle CPUs. Since tx scheduling work is very latency sensitive and kept short via AQL, sched_set_fifo_low is used to keep worker priority above normal tasks Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: rely on AQL for burst size limits on tx queueingFelix Fietkau
Now that AQL works well on all mt76 drivers, completely replace the arbitrary burst sizing and number of bursts logic for tx scheduling. For the short period of time in which AQL does not work well yet, limit each stations to 16 in-flight packets that have no estimated tx time. This should avoid filling the queue if a station connects and queues up a large number of packets before rate control information is available, especially with hardware rate control Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7615: significantly reduce interrupt loadFelix Fietkau
On 7615 and newer, DMA completion only triggers unmap, but not free of queued skbs, since pointers to packets are queued internally. Because of that, there is no need to process the main data queue immediately on DMA completion. To improve performance, mask out the DMA data queue completion interrupt and process the queue only when we receive a txfree event. This brings the number of interrupts under load down to a small fraction. Signed-off-by: Felix Fietkau <nbd@nbd.name>
