1	Linux* Base Driver for Intel(R) Ethernet Network Connection
2	===========================================================
4	Intel Gigabit Linux driver.

14	This file describes the igbvf Linux* Base Driver for Intel Network Connection.
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.
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.
25	The guest OS loading the igbvf driver must support MSI-X interrupts.
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.
33	Instructions on updating ethtool can be found in the section "Additional
34	Configurations" later in this document.
36	VLANs: There is a limit of a total of 32 shared VLANs to 1 or more VFs.
38	Identifying Your Adapter
39	========================
41	The igbvf driver supports 82576-based virtual function devices that can only
42	be activated on kernels that support SR-IOV.
44	For more information on how to identify your adapter, go to the Adapter &
45	Driver ID Guide at:
47	    http://support.intel.com/support/go/network/adapter/idguide.htm
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:

55	Additional Configurations
56	=========================
58	  ethtool
59	  -------
60	  The driver utilizes the ethtool interface for driver configuration and
61	  diagnostics, as well as displaying statistical information.  The ethtool
62	  version 3.0 or later is required for this functionality, although we
63	  strongly recommend downloading the latest version at:
65	  https://www.kernel.org/pub/software/network/ethtool/
67	Support
68	=======
70	For general information, go to the Intel support website at:
72	    http://support.intel.com
74	or the Intel Wired Networking project hosted by Sourceforge at:
76	    http://sourceforge.net/projects/e1000
78	If an issue is identified with the released source code on the supported
79	kernel with a supported adapter, email the specific information related
80	to the issue to e1000-devel@lists.sf.net
