Subject[PATCH v1 1/2] mt76: mt7615: rework set_channel function
Date
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.

Signed-off-by: Ryder Lee <ryder.lee@mediatek.com>
---
Changes since v1:
- add MCU_EXT_CMD_SET_RX_PATH to avoid creating a regression
