DESCRIPTION
This file contains the board-specific routines for Ethernet adapter
initialisation of Intel Pro 100+ adapters.

NOTE
At the time of writing, this module has only been tested with the following
Ethernet cards:
    82559 controller: Intel PRO/100+ Management Adapter
    82559ER chip    : Intel PRO/100+ chip on motherboard

Refer to the BSP man page for any eventual limitations or problems related
to the BSP.
