Subject: [PATCH 4.19 34/48] net: ethernet: mtk_eth_soc: fix MTU warnings
Date: Mon, 10 Aug 2020 17:21:56 +0200	[thread overview]
Message-ID: <20200810151805.896505636@linuxfoundation.org> (raw)
In-Reply-To: <20200810151804.199494191@linuxfoundation.org>

From: Landen Chao <landen.chao@mediatek.com>

[ 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")
