PATCH: sundance #4

while I was in there, and because it was easy, I ripped out the 
hand-coded ethtool stuff, and modernized a bit.  note that the lines 
that don't appear to have changes are lines which have been stripped of 
trailing whitespace.

Next, the issues that Jason pointed out with the hand-rolled RX polling, 
and the stuff Donald pointed out in his first message.
