| Subject: net/mlx5e: allow TSO on VXLAN over VLAN topologies |
| |
| From: Davide Caratti <dcaratti@redhat.com> |
| |
| [ 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). |
