I saw you committed this over the weekend, so I will updated my patches to 
account for this.  So far I have only had two issues:

1) TSO is broken.  However, this is probably due to the descriptor format.  I 
will try it again after merging in the FE+ changes.

2) I was getting RX overrun errors when pulling data over gige (at work) 
(pulling data == using csup to download the CVS repository for the first 
time).  It would die with an RX overrun every few minutes.  It required an 
ifconfig down/up to recover.  (It would be nice if the driver recovered from 
an RX overrun better perhaps.)  At home I only have a 10/100 network and the 
driver worked fine (finished full csup w/o any RX overruns) at 100.  I will 
also see if I can still reproduce this after merging in the FE+ changes over 
the weekend.
