Subject: [PATCH 6.8 237/715] wifi: mt76: mt7925: fix wmm queue mapping

From: Ming Yen Hsieh <mingyen.hsieh@...iatek.com>

[ Upstream commit 9d89edb576e385267f40193bd3776157101a504a ]

Firmware uses access class index (ACI) for wmm parameters update,
so convert mac80211 queue to ACI in mt7925_conf_tx().
