I'm using tcpdump3.0.2 with linux-1.3.72 to try
to look at the problems I'm seeing with TCP and UDP.
tcpdump is telling me that I have truncated packets.

My question is, is this because the snooper is truncating data, or do
I have a real ip truncation? I don't see any error printk() in the
system log from the networking code.
Thoughts?
