| 4262 | * When this api is called either through user sysfs, the driver shall |
| 4263 | * try to enable or disable SR-IOV virtual functions according to the |
| 4264 | * following: |
| 4265 | * |
| 4266 | * If zero virtual function has been enabled to the physical function, |
| 4267 | * the driver shall invoke the pci enable virtual function api trying |
| 4268 | * to enable the virtual functions. If the nr_vfn provided is greater |
| 4269 | * than the maximum supported, the maximum virtual function number will |
| 4270 | * be used for invoking the api; otherwise, the nr_vfn provided shall |
| 4271 | * be used for invoking the api. If the api call returned success, the |
| 4272 | * actual number of virtual functions enabled will be set to the driver |
| 4273 | * cfg_sriov_nr_virtfn; otherwise, -EINVAL shall be returned and driver |
| 4274 | * cfg_sriov_nr_virtfn remains zero. |
| 4275 | * |
| 4276 | * If none-zero virtual functions have already been enabled to the |
| 4277 | * physical function, as reflected by the driver's cfg_sriov_nr_virtfn, |
| 4278 | * -EINVAL will be returned and the driver does nothing; |
| 4279 | * |
| 4280 | * If the nr_vfn provided is zero and none-zero virtual functions have |
| 4281 | * been enabled, as indicated by the driver's cfg_sriov_nr_virtfn, the |
| 4282 | * disabling virtual function api shall be invoded to disable all the |
| 4283 | * virtual functions and driver's cfg_sriov_nr_virtfn shall be set to |
| 4284 | * zero. Otherwise, if zero virtual function has been enabled, do |
| 4285 | * nothing. |
| 4286 | * |
