Subject: [PATCH] net: ethernet: mtk_eth_soc: do not overwrite mtu
|
|
configuration running reset routine
|
|
|
|
Restore user configured MTU running mtk_hw_init() during tx timeout routine
|
|
since it will be overwritten after a hw reset.
|
|
|
|
Reported-by: Felix Fietkau <nbd@nbd.name>

Fixes: 9ea4d311509f ("net: ethernet: mediatek: add the whole ethernet reset into the reset process")
