| Subject: net/mlx5: Decrease default mr cache size |
| |
| [ Upstream commit e8b26b2135dedc0284490bfeac06dfc4418d0105 ] |
| |
| Delete initialization of high order entries in mr cache to decrease initial |
| memory footprint. When required, the administrator can populate the |
| entries with memory keys via the /sys interface. |
| |
| This approach is very helpful to significantly reduce the per HW function |
| memory footprint in virtualization environments such as SRIOV. |

| Fixes: 9603b61de1ee ("mlx5: Move pci device handling from mlx5_ib to mlx5_core") |
