[PATCH v4 08/25] mt76: mt7615: move mt7615_mcu_set_bmc to mt7615_mcu_ops

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Move mt7615_mcu_set_bmc for fw version 1 and version 2 in
mt7615_mcu_ops data structure. This is a preliminary patch
to properly support mt7663e firmware.
Rework utility routines to rely on skb APIs for msg parsing
