Public bug reported:
Binary package hint: linux-image-2.6.24-19-server
/sbin/ifconfig reports TX usage (amount of sent data), but at 4GB it
becomes zero
so all our stats are wrong (in hobbit for example)
============================================================
This trivial script is launched on our nfs server, while a nfs-client is
getting data:
while true ; do LANG=C date; LANG=C ifconfig eth0 | grep TX; echo; sleep
5; done >/tmp/TX.log
