Subject: openvswitch: Set internal device max mtu to ETH_MAX_MTU.

From: Jarno Rajahalme <jarno@ovn.org>


[ Upstream commit 425df17ce3a26d98f76e2b6b0af2acf4aeb0b026 ]

Commit 91572088e3fd ("net: use core MTU range checking in core net
infra") changed the openvswitch internal device to use the core net
infra for controlling the MTU range, but failed to actually set the
max_mtu as described in the commit message, which now defaults to
ETH_DATA_LEN.

This patch fixes this by setting max_mtu to ETH_MAX_MTU after
ether_setup() call.
