We do understand that this is not the ideal solution and most likely will be redone with a more generic offload framework. But this certainly will enable us to start seeing benefits of the accelerations for Geneve tunnels. As a side note, we did find an existing issue in i40e driver where a service task can modify tunnel data structures with no locks held to help linearize access. A separate patch will be taking care of that issue. A question out to the community is regarding the driver Kconfig parameters for VxLAN and Geneve, it would be ideal to drop those if there is a way to help resolve vxlan/geneve_get_rx_port symbols while the tunnel modules are not loaded.
