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")
