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: mt76x02u: Add support for newer versions of the XBox One wifi adapterMatthew Garrett
The current version has a new USB ID and reports as an 0x7632 device. Adding the IDs results in it working out of the box. Signed-off-by: Matthew Garrett <mjg59@google.com> 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>
2020-02-14mt76: mt76x2: avoid starting the MAC too earlyFelix Fietkau
Do not set the tx/rx start bits in MT_MAC_SYS_CTRL from within initvals. The driver sets these later when the hardware is ready Signed-off-by: Felix Fietkau <nbd@nbd.name>
