From: René van Dorst <opensource@vdorst.com>
in recent Kernel-Versions there are warnings about incorrect MTU-Size like these:
mt7530 mdio-bus:00: nonfatal error -95 setting MTU on port x 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") Signed-off-by: René van Dorst <opensource@vdorst.com> Signed-off-by: Frank Wunderlich <frank-w@public-files.de> --- changes in v2: Fixes: tag show 12-chars of sha1 and moved above other tags --- drivers/net/ethernet/mediatek/mtk_eth_soc.c | 4 ++++ 1 file changed, 4 insertions(+)
