| 14 | This file describes the igbvf Linux* Base Driver for Intel Network Connection. |
| 15 | |
| 16 | The igbvf driver supports 82576-based virtual function devices that can only |
| 17 | be activated on kernels that support SR-IOV. SR-IOV requires the correct |
| 18 | platform and OS support. |
| 19 | |
| 20 | The igbvf driver requires the igb driver, version 2.0 or later. The igbvf |
| 21 | driver supports virtual functions generated by the igb driver with a max_vfs |
| 22 | value of 1 or greater. For more information on the max_vfs parameter refer |
| 23 | to the README included with the igb driver. |
| 24 | |
| 25 | The guest OS loading the igbvf driver must support MSI-X interrupts. |
| 26 | |
| 27 | This driver is only supported as a loadable module at this time. Intel is |
| 28 | not supplying patches against the kernel source to allow for static linking |
| 29 | of the driver. For questions related to hardware requirements, refer to the |
| 30 | documentation supplied with your Intel Gigabit adapter. All hardware |
| 31 | requirements listed apply to use with Linux. |
| 32 | |
| 33 | Instructions on updating ethtool can be found in the section "Additional |
| 34 | Configurations" later in this document. |
| 35 | |
| 36 | VLANs: There is a limit of a total of 32 shared VLANs to 1 or more VFs. |

| 41 | The igbvf driver supports 82576-based virtual function devices that can only |
| 42 | be activated on kernels that support SR-IOV. |

| 58 | Ethtool |
| 59 | ------- |
| 60 | The driver utilizes the ethtool interface for driver configuration and |

| 62 | version 3.0 or later is required for this functionality, although we |
| 63 | strongly recommend downloading the latest version at: |
