I custom-renamed my network card to lan with a udev rule, yours would likely show up as eth1 or similar. I think rx_pause was very very high due to the cheating switch. If your laptop doesn't have a gigabit ethernet port, you won't see it at all.

Of course, this being switched traffic, you may not see any of that unless the traffic is between the linux machine and the AIX host, rather than between different hosts..

I plugged my Windows XP laptop into the same gigabit switch my AIX boxes are plugged into and when I map my Windows share from my AIX box, I can still only transfer 2 or 3 MB/s. It is negotiating the something wrong at the protocol level.
