| Subject: net/mlx5e: fix ingress_ifindex check in mlx5e_flower_parse_meta |
| |
| From: wenxu <wenxu@ucloud.cn> |
| |
| commit e3e0f9b279705154b951d579dc3d8b7041710e24 upstream. |
| |
| In the nft_offload there is the mate flow_dissector with no |
| ingress_ifindex but with ingress_iftype that only be used |
| in the software. So if the mask of ingress_ifindex in meta is |
| 0, this meta check should be bypass. |
| |
| Fixes: 6d65bc64e232 ("net/mlx5e: Add mlx5e_flower_parse_meta support") |
