I read through the IGB driver, and it says 82575/6 only... which is the
new chip Intel is releasing on the cards this month 2 port
and october 4 port, but the chips are on some of the motherboards right now.
Why can't it also use the 82571 ? doesn't make any sense.. I haven't
tried it but just browsing the driver source
doesn't look like it will work.
