From f00e6f8bc9081f158b7d6a1dcfa82218b1dbfb4d Mon Sep 17 00:00:00 2001 From: Michal Privoznik Date: Thu, 8 Jun 2017 10:14:36 +0200 Subject: [PATCH] qemu: Set iface MTU on hotplug https://bugzilla.redhat.com/show_bug.cgi?id=1408701 While implementing MTU (572eda12ad and friends), I've forgotten to actually set MTU on the host NIC in case of hotplug. We correctly tell qemu on the monitor what the MTU should be, but we are not actually setting it on the host NIC.
