From 0ae37bb09bc282c6bca9e425990685cef6a9b1b6 Mon Sep 17 00:00:00 2001 Message-Id: <0ae37bb09bc282c6bca9e425990685cef6a9b1b6@dist-git> From: Michal Privoznik Date: Thu, 8 Jun 2017 16:58:35 +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.
