+Subject: [PATCH 075/116] mtk: wifi: mt76: mt7996: get airtime and RSSI via MCU
+ commands
+
+Direct access to WTBL for airtime and RSSI may cause synchronization issue with FW.
+Moreover, frequent access to WTBL, whenever TX-Free-Done event is received, leads to heavy CPU overheads.
+Therefore, indirect access to WTBL, through FW, with lower frequence is performed.
