[PATCH net-next v3 05/10] devlink: Adding num MSI-X vectors per VF perm config param

[Steve Lin]

Adding DEVLINK_PERM_CONFIG_MSIX_VECTORS_PER_VF permanent config
parameter.  Value is permanent, so becomes the new default value
for this device.

Value defines number of MSI-X vectors allocated per VF.
