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: + + http://ftp.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 |
