Here is where we're at today:

rdma_resolve_addr:
	- Source sends a multicast request to destination IP
	- Destination performs a path record query
	- Destination sends a response with IP to DGID mapping

rdma_resolve_route:
	- Source performs a path record query

The current implementation of ACM converts this to:
	** Source sends a multicast request to destination IP
	** Destination sends a response with IP to DGID mapping
	- Path record is constructed from multicast group information	

ACM needs to know what the local addresses are, so it can respond to requests
for those addresses.
