From: Davide Caratti Date: Thu, 9 Jan 2020 11:07:59 +0000 (+0100) Subject: net/mlx5e: allow TSO on VXLAN over VLAN topologies X-Git-Tag: v5.4.128~72 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=946a36f82a0b21567e92f932832abdeb758bcc70;p=users%2Fdwmw2%2Flinux.git 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).
