 Hello!

 Honestly not too much thinking... well we can always argue by having
 Rx last we get more packets per poll. Yes we should test the other
 way around.

 Also still some concern by having the watchdog kicked in e1000_intr 
 wouldn't e1000_clean feel better? 

 It would also be interesting to see what happens if we remove the flush when 
 enable interrupts in e1000_clean?

 I've tested the patch that removes some of the PCI-accesses. I think I sent
 you some version of it. Anyway it seems to have some effects. If Jason has 
 time we will get some numbers from his instrument/setup.

 Cheers.
