Date: Tue, 17 May 2022 23:49:31 -0700 From: Saeed Mahameed <saeed@...nel.org> To: "David S. Miller" <davem@...emloft.net>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com> Cc: netdev@...r.kernel.org, Gal Pressman <gal@...dia.com>, Aya Levin <ayal@...dia.com>, Saeed Mahameed <saeedm@...dia.com> Subject: [net-next 09/16] net/mlx5e: Support partial GSO for tunnels over vlans From: Gal Pressman <gal@...dia.com> Offloading outer checksum on tunnels requires GSO partial, add it to 'vlan_features' to allow offloading tunnels over vlans. For example, running GENEVE over vlan & ipv6 (mandatory UDP checksum) now allows for hardware TSO instead of software segmentation in GSO only.
