+Subject: [PATCH 3/9] network: Add LLDP neighbors method to varlink server
+
+Add a method to varlink server that will allow streaming the list of
+LLDP neighbors on a particular link. The method's argument is the ifindex
+of a link. The method then streams the JSONs representing individual
+neighbors as discovered by the LLDP protocol.
