Subject: [PATCH v4] net: ethernet: mtk_eth_soc: fix MTU warnings
Date: Tue, 4 Aug 2020 18:55:50 +0200 [thread overview]
Message-ID: <20200804165555.75159-3-linux@fw-web.de> (raw)
In-Reply-To: <20200804165555.75159-1-linux@fw-web.de>
From: Landen Chao <landen.chao@mediatek.com>
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")
Signed-off-by: Landen Chao <landen.chao@mediatek.com>
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
Reviewed-by: Andrew Lunn <andrew@lunn.ch>

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)
