| Subject: RDMA/mlx5: Initiate dropless RQ for RAW Ethernet functions |
| |
| From: Maher Sanalla <msanalla@nvidia.com> |
| |
| [ Upstream commit ee4d269eccfea6c17b18281bef482700d898e86f ] |
| |
| Delay drop data is initiated for PFs that have the capability of |
| rq_delay_drop and are in roce profile. |
| |
| However, PFs with RAW ethernet profile do not initiate delay drop data |
| on function load, causing kernel panic if delay drop struct members are |
| accessed later on in case a dropless RQ is created. |
| |
| Thus, stage the delay drop initialization as part of RAW ethernet |
| PF loading process. |
