net/ipv6: Create a neigh_lookup for FIB entries
The router discovery code has a FIB entry and wants to validate the gateway has a neighbor entry. Refactor the existing dst_neigh_lookup for IPv6 and create a new function that takes the gateway and device and returns a neighbor entry. Use the new function in ndisc_router_discovery to validate the gateway. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
