+Subject: [PATCH] Avoid trying to delete inactive VIFs
+Organization: Westermo Network Technologies AB
+
+When probing interfaces at startup, there's a check for IFF_MULTICAST,
+if this flag is not set we try to delete its corresponding VIF/MIF.
+This is for hanlding .conf reload scenarios where an interface has had
+its MULTICAST flag dropped.
+
+However, when starting up on Linux systems, the loopback interface has
+no MULTICAST flag set.  This leads to the following bogus warning:
+
+   Failed deleting VIF for iface lo: Resource temporarily unavailable
+
+This patch makes sure to check if we have a registered kernel VIF/MIF
+for an interface before attempting to delete it.
