2020-05-12mt76: mt7663: add the possibility to load firmware v2Lorenzo Bianconi4-8/+57
mt7663 firmware v2 is used for embedded devices since it has more completed features in AP mode. Add the capability to specify which firmware load first (v3 or v2) using prefer_offload_fw kernel parameter and fallback to the other one if the selected firmware fails to load Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-05-12mt76: mt7615: fix event report in mt7615_mcu_bss_eventLorenzo Bianconi1-1/+2
Currently mt7663 devices do not support DBDC so fw events have no info about it. Fix mt7615_mcu_bss_event that wrongly use bss_idx as DBDC band_idx while it is vif index. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-05-12mt76: mt7663: fix up BMC entry indicated to unicmd firmwareSean Wang1-19/+3
BMC entry for MT7663 unicmd firmware should be a broadcast/multicast entry, not a unicast entry, that is GTK rekey offload would rely on.

2020-05-12mt76: fix A-MPDU density handlingFelix Fietkau3-3/+10
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>
