selftests: mlxsw: Add a test case for L3 VNI
Previous patch added the ability to offload a VXLAN tunnel used for L3 VNI when it is present in the VLAN-aware bridge before the corresponding VLAN interface is configured. This patch adds a test case to verify that. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
