Here I am again after long time. It seem that buffers were too short 8KiB and
messages can be up to 10KiB. Now I fixed this and it is stable. Unfortunately I
can't test on synthetic target since newer Linux kernel (3) doesn't seem to
support ethertap (any suggestion?).
Sergei do u have some time to test on synthetic target pse?

Note: The same bug with MAX_BUF seem to be present in BSD test too. I'm going
to open a bug for that.
