Re: [Linux-ia64] disabling nics in efi.

[Alex Williamson <alex_williamson@hp.com>]

   The EFI driver has nothing to do with whether the NIC shows up
to the OS.  It only makes it unavailble from EFI, the hardware is
still there.  I don't know of any way to make the NICs not show up
other than not loading the module.
