neigh: Add helper function neigh_xmit
For MPLS I am building the code so that either the neighbour mac address can be specified or we can have a next hop in ipv4 or ipv6. The kind of next hop we have is indicated by the neighbour table pointer. A neighbour table pointer of NULL is a link layer address. A non-NULL neighbour table pointer indicates which neighbour table and thus which address family the next hop address is in that we need to look up. The code either sends a packet directly or looks up the appropriate neighbour table entry and sends the packet. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S.
