The lanutil.efi utility is used to update the option ROM on Intel PCI and PCI-E
network adapters with a UEFI network driver image.  The utility can also be
used to disable and enable the option ROM or to configure adapter Wake-On-LAN
settings.

Usage:

lanutil [-up] [-nic=X|-all] [-wole|-wold] [-fe|-fd] [-blink] [-auto]

    -up         - Programs selected network port with a UEFI option ROM.
    -nic=X|-all - Selects a specific port or all ports to perform operations on.
    -wole|-wold - Enables or disables WOL on the selected port.
    -fe|-fd     - Enables/Disables boot ROM on the selected port.
    -blink      - Blinks the LED on the selected port.
    -auto       - Run all operations without confirmation prompts

Notes:
    1. If the -up parameter is specified without the -all or -nic=X
       parameters the utility will upgrade all networks ports previously
       programmed with an EFI option ROM.  The -all or -nic parameters
       must be specified to reprogram an adapter that was not previously
       programmed with a UEFI driver.
    2. If called with no command line parameters a list of all supported Intel
       network connections will be displayed.
    3. lanutil cannot program LAN-on-motherboard (LOM) network connections
       with an EFI option ROM image. To use the EFI network driver on a
       LOM based network connection the driver must be loaded from a
       local disk partition using the shell "load" command, or be built
       into the platform EFI implementation by the platform vendor.

Examples:
    * To force an update of all Intel network adapters found in the system
      to the UEFI network driver ROM image embedded in the utility with no
      confirmation prompts (WARNING: This operation will erase an Intel Boot
      Agent or iSCSI Boot option ROM image from the network adapter):
      fs0:\> lanutil -up -auto -all

    * To update only the Intel Network Connections which have been
      previously programmed with an UEFI driver image:
      fs0:\> lanutil -up

    * To disable the option ROM on port 1 to prevent the UEFI option ROM
      from loading during system boot:
      fs0:\> lanutil -nic=1 -fd

    * To identify physical port 2 by using the LED blink function:
      fs0:\> lanutil -nic=2 -blink

    * To disable Wake-On-LAN on all Intel Network Connections in the system:
      fs0:\> lanutil -all -wold
