2020-12-04mt76: move tx hw data queues in mt76_phyLorenzo Bianconi1-2/+2
Move hw data queues in mt76_phy from mt76_dev since mt7915 supports per phy hw queues in dbdc mode Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: remove struct mt76_sw_queueFelix Fietkau1-1/+1
All members except for the struct mt76_queue pointer have been removed Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: rely on AQL for burst size limits on tx queueingFelix Fietkau1-5/+4
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>
2020-07-21mt76: rely on register macrosLorenzo Bianconi1-2/+2
For consistency with the rest of the code always rely on defined macros for register access Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-07-21mt76: usb: rely on mt76_for_each_q_rxLorenzo Bianconi1-3/+0
