- Subject: [PATCH] net: ethernet: mtk_eth_soc: fix WED + wifi reset
- The WLAN + WED reset sequence relies on being able to receive interrupts from
- the card, in order to synchronize individual steps with the firmware.
- When WED is stopped, leave interrupts running and rely on the driver turning
- off unwanted ones.
- WED DMA also needs to be disabled before resetting.
- Fixes: f78cd9c783e0 ("net: ethernet: mtk_wed: update mtk_wed_stop")
- Signed-off-by: Felix Fietkau <[email protected]>
