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. | ||
37 | |||
38 | Identifying Your Adapter | ||
39 | ======================== | ||
40 | |||
41 | The igbvf driver supports 82576-based virtual function devices that can only | ||
42 | be activated on kernels that support SR-IOV. | ||
43 | |||
44 | For more information on how to identify your adapter, go to the Adapter & | ||
45 | Driver ID Guide at: | ||
46 | |||
47 | http://support.intel.com/support/go/network/adapter/idguide.htm | ||
48 | |||
49 | For the latest Intel network drivers for Linux, refer to the following | ||
50 | website. In the search field, enter your adapter name or type, or use the | ||
51 | networking link on the left to search for your adapter: | ||

54 | |||
55 | Additional Configurations | ||
56 | ========================= | ||
57 | |||
58 | Ethtool | ||
59 | ------- | ||
60 | The driver utilizes the ethtool interface for driver configuration and | ||
61 | diagnostics, as well as displaying statistical information. | ||

65 | Support | ||
66 | ======= | ||
67 | |||
68 | For general information, go to the Intel support website at: | ||
69 | |||

75 | |||
76 | If an issue is identified with the released source code on the supported | ||
77 | kernel with a supported adapter, email the specific information related | ||
78 | to the issue to e1000-devel@lists.sf.net | ||
