selftests: forwarding: Add helpers and tests for FIB offload
Implement a set of common helpers and tests for FIB offload that can be used by multiple drivers to check their FIB offload implementations. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
