2021-10-20mt76: disable BH around napi_schedule() callsFelix Fietkau
napi_schedule() can call __raise_softirq_irqoff(), which can perform softirq handling, so it must not be called in a pure process context with BH enabled. 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.

2019-09-03mt76: mt76x0e: don't use hw encryption for MT7630EStanislaw Gruszka
Since 41634aa8d6db ("mt76: only schedule txqs from the tx tasklet") I can observe firmware hangs on MT7630E on station mode: tx stop functioning after minor activity (rx keep working) and on module unload device fail to stop with messages: [ 5446.141413] mt76x0e 0000:06:00.0: TX DMA did not stop [ 5449.176764] mt76x0e 0000:06:00.0: TX DMA did not stop Loading module again results in failure to associate with AP. Only machine power off / power on cycle can make device work again. It's unclear why commit 41634aa8d6db causes the problem, but it is related to HW encryption. Since issue is a firmware hang, that is super hard to debug, just disable HW encryption as fix for the issue.

2019-05-01mt76: mt76x02: remove bogus mutex usageStanislaw Gruszka

This fixes possible deadlock on cancel_delayed_work_sync(&dev->mac_work) as mac_work also take mutex.
