+Subject: [PATCH] BGP: Fix handling of strange IPv6 link-local-only next hops
+
+There are three common ways how to encode IPv6 link-local-only next hops:
+(:: ll), (ll), and (ll ll). We use the first one but we should accept all
+three. The patch fixes handling of the last one.
+
+Thanks to Sebastian Hahn for the bugreport.
