Hi

I get these when doing TCP transfers with gensink running around 70MB/s
using jumbo frames between two 2.4.0-test10 boxes (with 1MB alteon-based
cards on both ends). 

It's a bit random, when I run the test there's sometimes hundreds of these,
then when I run it again there's no problems at all. 

I put a tcpdump (about 1M) of this in session in 
http://ppieta.home.cern.ch/ppieta/dump.gz 

TCP: peer 192.168.9.2:5001/1029 shrinks window 2050038622:599504:2050638138.
Bad, what else can I say?
