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>

2020-05-12mt76: mt76x02: fix handling MCU timeouts during hw restartFelix Fietkau
If a MCU timeout occurs before a hw restart completes, another hw restart is scheduled, and the station state gets corrupted. To speed up dealing with that, do not issue any MCU commands after the first timeout, and defer handling timeouts until the reset has completed. Also ignore errors in MCU commands during start/config to avoid making user space fail on this condition. If it happens, another restart is scheduled quickly, and that usually recovers the hardware properly. Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-11-20Revert "mt76: mt76x0e: don't use hw encryption for MT7630E"Stanislaw Gruszka
This reverts commit 34b0e9b767bfa09ae233ca0d6ceb299bf2e24600. Since commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs") is no longer necessary to disable HW encryption for MT7630E. Disabling HW encryption helped previously because somehow fragmented skb's are not created if mac80211 encrypt frames, so buffer unmap bug of non-linear skbs was not triggered. Now since this bug is properly fixed by commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs") , we can enable HW encryption back.
