Linux* Base Driver for Intel(R) Ethernet Network Connection =========================================================== Intel Gigabit Linux driver. Copyright(c) 1999 - 2013 Intel Corporation. Contents ======== - Identifying Your Adapter - Additional Configurations - Support This file describes the igbvf Linux* Base Driver for Intel Network Connection. The igbvf driver supports 82576-based virtual function devices that can only be activated on kernels that support SR-IOV. SR-IOV requires the correct platform and OS support. The igbvf driver requires the igb driver, version 2.0 or later. The igbvf driver supports virtual functions generated by the igb driver with a max_vfs value of 1 or greater. For more information on the max_vfs parameter refer to the README included with the igb driver. The guest OS loading the igbvf driver must support MSI-X interrupts. This driver is only supported as a loadable module at this time. Intel is not supplying patches against the kernel source to allow for static linking of the driver. For questions related to hardware requirements, refer to the documentation supplied with your Intel Gigabit adapter. All hardware requirements listed apply to use with Linux. Instructions on updating ethtool can be found in the section "Additional Configurations" later in this document. VLANs: There is a limit of a total of 32 shared VLANs to 1 or more VFs. Identifying Your Adapter ======================== The igbvf driver supports 82576-based virtual function devices that can only be activated on kernels that support SR-IOV. For more information on how to identify your adapter, go to the Adapter & Driver ID Guide at: http://support.intel.com/support/go/network/adapter/idguide.htm For the latest Intel network drivers for Linux, refer to the following website. In the search field, enter your adapter name or type, or use the networking link on the left to search for your adapter: http://downloadcenter.intel.com/scripts-df-external/Support_Intel.aspx Additional Configurations ========================= ethtool ------- The driver utilizes the ethtool interface for driver configuration and diagnostics, as well as displaying statistical information. The ethtool version 3.0 or later is required for this functionality, although we strongly recommend downloading the latest version at: https://www.kernel.org/pub/software/network/ethtool/ Support ======= For general information, go to the Intel support website at: http://support.intel.com or the Intel Wired Networking project hosted by Sourceforge at: http://sourceforge.net/projects/e1000 If an issue is identified with the released source code on the supported kernel with a supported adapter, email the specific information related to the issue to e1000-devel@lists.sf.net
