| Subject: net/mlx4_core: Don't issue PCIe speed/width checks for |
| VFs |
| |
| From: Eyal Perry <eyalpe@mellanox.com> |
| |
| [ Upstream commit 83d3459a5928f18c9344683e31bc2a7c3c25562a ] |
| |
| Carrying out PCI speed/width checks through pcie_get_minimum_link() |
| on VFs yield wrong results, so remove them. |
| |
| Fixes: b912b2f ('net/mlx4_core: Warn if device doesn't have enough PCI bandwidth') |
