Subject: net: ethernet: mtk_eth_soc: fix MTU warnings
From: Landen Chao <landen.chao@xxxxxxxxxxxx>
[ Upstream commit 555a893303872e044fb86f0a5834ce78d41ad2e2 ]
in recent kernel versions there are warnings about incorrect MTU size
like these:
eth0: mtu greater than device maximum
mtk_soc_eth 1b100000.ethernet eth0: error -22 setting MTU to include DSA overhead
Fixes: bfcb813203e6 ("net: dsa: configure the MTU for switch ports")
Fixes: 72579e14a1d3 ("net: dsa: don't fail to probe if we couldn't set the MTU")
Fixes: 7a4c53bee332 ("net: report invalid mtu value via netlink extack")
