on irnet2 (Libretto 50) irtty=/dev/ttyS0
- netserver
- ping irnet1
on irnet1 (Libretto 100) toshoboe-2.13
- batch with netperf -H irnet2
=================================
ping time on an idle link is not significant:

=================================
when netperf is working with default data, ping make no error, sometimes one error.
when netperf is working with a zipped file, ping make many errors
