mt76: mt7615: fix hw queue mapping
mt7622/mt7663 chipsets rely on a fixed reverse queue map order respect to mac80211 one: - q(0): IEEE80211_AC_BK - q(1): IEEE80211_AC_BE - q(2): IEEE80211_AC_VI - q(3): IEEE80211_AC_VO Fixes: cdad4874057d ("mt76: mt7615: add dma and tx queue initialization for MT7622") Fixes: f40ac0f3d3c0 ("mt76: mt7615: introduce mt7663e support") Co-developed-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Sean Wang <sean.wang@mediatek.com> Co-developed-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
