+define Package/bfdd/description
+  A port of Cumulus BFD daemon to a more portable daemon.
+
+  Bidirectional Forwarding Detection (BFD) is a network protocol that is used to
+  detect faults between two forwarding engines connected by a link. It provides
+  low-overhead detection of faults even on physical media that doesn't support
+  failure detection of any kind, such as Ethernet, virtual circuits, tunnels and
+  MPLS Label Switched Paths.
