| 4768 | * Description: |
| 4769 | * When this api is called either through user sysfs, the driver shall |
| 4770 | * try to enable or disable SR-IOV virtual functions according to the |
| 4771 | * following: |
| 4772 | * |
| 4773 | * If zero virtual function has been enabled to the physical function, |
| 4774 | * the driver shall invoke the pci enable virtual function api trying |
| 4775 | * to enable the virtual functions. If the nr_vfn provided is greater |
| 4776 | * than the maximum supported, the maximum virtual function number will |
| 4777 | * be used for invoking the api; otherwise, the nr_vfn provided shall |
| 4778 | * be used for invoking the api. If the api call returned success, the |
| 4779 | * actual number of virtual functions enabled will be set to the driver |
| 4780 | * cfg_sriov_nr_virtfn; otherwise, -EINVAL shall be returned and driver |
| 4781 | * cfg_sriov_nr_virtfn remains zero. |
| 4782 | * |
| 4783 | * If none-zero virtual functions have already been enabled to the |
| 4784 | * physical function, as reflected by the driver's cfg_sriov_nr_virtfn, |
| 4785 | * -EINVAL will be returned and the driver does nothing; |
| 4786 | * |
| 4787 | * If the nr_vfn provided is zero and none-zero virtual functions have |
| 4788 | * been enabled, as indicated by the driver's cfg_sriov_nr_virtfn, the |
| 4789 | * disabling virtual function api shall be invoded to disable all the |
| 4790 | * virtual functions and driver's cfg_sriov_nr_virtfn shall be set to |
| 4791 | * zero. Otherwise, if zero virtual function has been enabled, do |
| 4792 | * nothing. |
| 4793 | * |
| 4794 | * Returns: |
| 4795 | * length of the buf on success if val is in range the intended mode |
| 4796 | * is supported. |
| 4797 | * -EINVAL if val out of range or intended mode is not supported. |
