+Subject: [PATCH] ifupdown: support 'link' address family
+
+Does not configure anything. L2 configuration hook scripts should do
+their job on receiving ADDRFAM=link. Configuration will be done only
+once, irrespective of L3 protocols used.
+
+Using the 'link' family in the interfaces file conforms to the Debian
+implementation:
+
+http://sources.debian.net/src/ifupdown/0.7.47.1/link.defn
