Two Intel Pro/100+ Management Adapters from Intel for $40

[Manfred Young]

The guys I talked to at Intel did said that we would have to make some
changes to our driver for the 82559. Hopefully it will just mean a few
changes to the configuration bytes. I'm waiting for a copy of the Software
Technical Reference manual from the 82559 from Intel (document number
OR1681). It's supposed to outline the differences between the 82557, 82558
and 82559.
