io_stat is really dumb when it sees packets where timestamps have
non-monotonic growth.
it just discards the packet if the timestamp has not increased from the
previous one.

if this shows to be a problem in that it causes it to drop/ignore too many
packets, one can try
to make it handle these packets more intelligently.
