mlxsw: spectrum_router: Implement next-hop routing
Implement next-hop routing offload including ECMP. To make it possible, introduce next-hop group entity. This entity keeps track of resolved neighbours and updates HW adjacency table accordingly. Note that HW next-hops are stored in this adjacency table, in form of MAC. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
