  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:

  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/
