From 94affdf9f917ab56b455cde3ed1eefa0c18f16f3 Mon Sep 17 00:00:00 2001 From: Jarno Rajahalme Date: Tue, 14 Feb 2017 21:16:28 -0800 Subject: [PATCH] openvswitch: Set internal device max mtu to ETH_MAX_MTU. Commit b8d55c187b83 ("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.
