Subject: [PATCH AUTOSEL 4.19 22/59] ip6erspan: remove the incorrect mtu limit for ip6erspan
Date: Sat, 26 Oct 2019 09:18:33 -0400 [thread overview]
Message-ID: <20191026131910.3435-22-sashal@kernel.org> (raw)
In-Reply-To: <20191026131910.3435-1-sashal@kernel.org>
From: Haishuang Yan <yanhaishuang@cmss.chinamobile.com>
[ Upstream commit 4123f637a5129470ff9d3cb00a5a4e213f2e15cc ]
ip6erspan driver calls ether_setup(), after commit 61e84623ace3
("net: centralize net_device min/max MTU checking"), the range
of mtu is [min_mtu, max_mtu], which is [68, 1500] by default.
It causes the dev mtu of the erspan device to not be greater
than 1500, this limit value is not correct for ip6erspan tap
device.
Fixes: 61e84623ace3 ("net: centralize net_device min/max MTU checking")
