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")

v3->v4
  - fix commit-message (hyphernations,capitalisation) as suggested by Russell
  - add Signed-off-by Landen
  - dropped wrong signed-off from rene (because previous v1/2 was from him)

Applied, thank you.
