In the addressvirtual module we have some code that checks if stale macvlans should be deleted (when the address-virtual or vrrp keywords are removed from the config). To find those stale macvlans we basically do a glob search in /sys/class/net/ with the macvlan prefix (ifname) defined by ifupdown2: '%s-v' % ifaceobj.name[0:13], which for a device foo would create macvlans named foo-v0...foo-vN. In this particular case we have a vxlan named: sha3szx4-vpn, which gets matched and removed without actually checking if this device is a macvlan or not. This commit adds a link_kind check to ensure that we are only removing macvlans. Signed-off-by: Julien Fortin <julien@cumulusnetworks.com>
