If you want to capture olsr PACKETs from your one-hop neighbors just use 
tcpdump. Packets are one traveling one hop.

For capturing only 1-hop MESSAGES, you could install another message listener 
in OLSR as a plugin and check every incoming message if it's originator-IP 
belongs to a one-hop neighbor (checking against the neighbor set would be the 
easiest way I think).

You can use olsr_parser_add_function() (see src/parser.c) to add your callback 
for a specific message type (use PROMISCUOUS as message type to get them all).
