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

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