With RFC 5549 we need a methodology to find a neighbor based upon a nexthop that is v6 based. This commit sets us up for that by allowing you to find the neigbor by the secondary list. In a future commit we will add code to pass the v6 secondary addresses. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
