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. | |

60 | The driver utilizes the ethtool interface for driver configuration and | |
68f20d94 | 61 | diagnostics, as well as displaying statistical information. The ethtool |
f2be1429 JK |
62 | version 3.0 or later is required for this functionality, although we |
63 | strongly recommend downloading the latest version at: | |
