Subject: [PATCH 1/2] mt76: mt7615: rework set_channel function
Date: Sun, 15 Dec 2019 11:56:31 +0800	[thread overview]
Message-ID: <d3d47e29e2a39c42adfcf912a27b9d19a01d5010.1576381077.git.ryder.lee@mediatek.com> (raw)

No need to send both MCU_EXT_CMD_SET_RX_PATH and MCU_EXT_CMD_CHANNEL_SWITCH
together to MCU.

Split them out by passing the proper command in the corresponding flow.
