net/mlx5e: allow TSO on VXLAN over VLAN topologies
[ Upstream commit a1718505d7f67ee0ab051322f1cbc7ac42b5da82 ]
since mlx5 hardware can segment correctly TSO packets on VXLAN over VLAN
topologies, CPU usage can improve significantly if we enable tunnel
offloads in dev->vlan_features, like it was done in the past with other
NIC drivers (e.g. mlx4, be2net and ixgbe).
