[libvirt] [PATCH] qemu, util fix netlink callback registration for migration

From: "D. Herrendoerfer" <d.herrendoerfer(a)herrendoerfer.name&gt; This patch adds a netlink callback when migrating a VEPA enabled virtual machine. It fixes a Bug where a VM would not request a port association when it was cleared by lldpad. This patch requires the latest git version of lldpad to work. Signed-off-by: D.
