+Subject: [PATCH 7/8] Mark deleted interfaces as being changed
+
+Netlink notification handling ignores messages for deleted links,
+RTM_DELLINK. It does handle RTM_GETLINK. According to libnl docu-
+mentation (http://www.infradead.org/~tgr/libnl/doc/route.html)
+RTM_DELLINK can be sent by the kernel, but RTM_GETLINK cannot.
+There was likely a mixup in the original implementation, so this
+change replaces handling for RTM_GETLINK with RTM_DELLINK.
+
+Testing and Verification Instructions:
+  1. Use ip-link to add and remove a VLAN interface and verify
+     that mDNSResponder handles the deleted link.
+
