| Subject: net/mlx5e: Enable XDP for Connect-X IPsec capable devices |
| |
| From: Raed Salem <raeds@nvidia.com> |
| |
| [ Upstream commit e33f9f5f2d3a5fa97728a43708f41da2d4faae65 ] |
| |
| This limitation was inherited by previous Innova (FPGA) IPsec |
| implementation, it uses its private set of RQ handlers which |
| does not support XDP, for Connect-X this is no longer true. |
| |
| Fix by keeping this limitation only for Innova IPsec supporting devices, |
| as otherwise this limitation effectively wrongly blocks XDP for all |
| future Connect-X devices for all flows even if IPsec offload is not |
| used. |
| |
| Fixes: 2d64663cd559 ("net/mlx5: IPsec: Add HW crypto offload support") |
