2020-05-12mt76: mt7615: do not adjust MAC timings if the device is not runningFelix Fietkau
Avoids register writes and MAC start/stop when the hardware isn't ready for it Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: mt7615: adjust timing in mt7615_mac_set_timing to match fw/hw valuesFelix Fietkau
Slightly improves performance Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: mt7603: never use an 802.11b CF-End rate on 5GHzFelix Fietkau
Sometimes mt7615_mac_set_timing gets called while the slot time is still configured to 20. Ensure that in this case it always uses the OFDM CFend rate. Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-05-12mt76: mt7615: use larger rx buffers if VHT is supportedFelix Fietkau
In VHT mode we can receive larger MPDUs. Increasing the buffer size reduces fragmentation here, which should improve performance. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: fix A-MPDU density handlingFelix Fietkau
The hardware requirements for A-MPDU density are entirely on the tx side, not the rx side. Because of that, the IE value should stay at 0 and the minimum value should instead be enforced in WTBL/TXWI MT7615 has no restrictions here Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: mt7615: fix sta ampdu factor for VHTFelix Fietkau
