If you try sending a large number of packets (e.g. using arping or a 
broadcast ping: anything that won't wait for a reply before sending out 
the next packet) then what happens to the TX packet counts and error 
counts reported by ifconfig?

Does tcpdump running on the notebook see its own transmitted packets?

Good to know, but it's probably going to be easier to try to diagnose 
the problem from within Linux first.
