  14Identifying Your Adapter
  15========================
  16
  17This driver supports all 82575, 82576 and 82580-based Intel (R) gigabit network
  18connections.
  19
  20For specific information on how to identify your adapter, go to the Adapter &
  21Driver ID Guide at:

  24
  25Command Line Parameters
  26=======================
  27
  28The default value for each parameter is generally the recommended setting,
  29unless otherwise noted.
  30
  31max_vfs
  32-------
  33Valid Range:   0-7
  34Default Value: 0
  35
  36This parameter adds support for SR-IOV.  It causes the driver to spawn up to
  37max_vfs worth of virtual function.
  38
  39
  40Additional Configurations
  41=========================
  42
  43  Jumbo Frames
  44  ------------
  45  Jumbo Frames support is enabled by changing the MTU to a value larger than
  46  the default of 1500.  Use the ifconfig command to increase the MTU size.
  47  For example:
  48
  49       ifconfig eth<x> mtu 9000 up
  50
  51  This setting is not saved across reboots.
  52
  53  Notes:
  54
  55  - The maximum MTU setting for Jumbo Frames is 9216.  This value coincides
  56    with the maximum Jumbo Frames size of 9234 bytes.
  57
  58  - Using Jumbo Frames at 10 or 100 Mbps may result in poor performance or
  59    loss of link.
  60
  61  Ethtool
  62  -------
  63  The driver utilizes the ethtool interface for driver configuration and
  64  diagnostics, as well as displaying statistical information. The latest
  65  version of ethtool can be found at:
  66
  67  http://ftp.kernel.org/pub/software/network/ethtool/
  68
  69  Enabling Wake on LAN* (WoL)
  70  ---------------------------
  71  WoL is configured through the ethtool* utility.
  72
  73  For instructions on enabling WoL with ethtool, refer to the ethtool man page.
  74
  75  WoL will be enabled on the system during the next shut down or reboot.
  76  For this driver version, in order to enable WoL, the igb driver must be
  77  loaded when shutting down or rebooting the system.
  78
  79  Wake On LAN is only supported on port A of multi-port adapters.
  80
  81  Wake On LAN is not supported for the Intel(R) Gigabit VT Quad Port Server
  82  Adapter.
  83
  84  Multiqueue
  85  ----------
  86  In this mode, a separate MSI-X vector is allocated for each queue and one
  87  for "other" interrupts such as link status change and errors.  All
  88  interrupts are throttled via interrupt moderation.  Interrupt moderation
