neigh: support to add fdb entry
rtnl_neigh.n_family should be set as AF_BRIDGE when we want to add a fdb entry,
but the func build_neigh_msg does not allow dst addr to be put at that time.
Here is the example:
struct rtnl_neigh *neigh = rtnl_neigh_alloc();
struct nl_addr *mac = nl_addr_build(AF_LLC, eth, ETH_ALEN);
struct nl_addr *dst = nl_addr_build(AF_INET, addr, 4);
rtnl_neigh_set_ifindex(neigh, rtnl_link_get_ifindex(vxlan_link));
rtnl_neigh_set_state(neigh, NUD_NOARP | NUD_PERMANENT);
rtnl_neigh_set_lladdr(neigh, mac);
rtnl_neigh_set_flags(neigh, NTF_SELF);
rtnl_neigh_set_dst(neigh, dst);
rtnl_neigh_set_family(neigh, AF_BRIDGE);
rtnl_neigh_add(sk, neigh, NLM_F_CREATE);
Then command "bridge fdb show" will print out the fdb entry:
