OK. Anyway NIC buffers restrict buffered packets number. But the problem
remain: why a (for exemple) dual Xeon E5520@2.27GHz with Intel PRO/1000
(82576) can't route 150kpps without Ierr :-)

Just an idea, but may be it very well could have something to do with this:
http://www.openbsd.org/want.html
Specifically this part:
# Intel 82576 SFP and 82580 based Gigabit Ethernet devices for improving
hardware support in em(4). Needed in Hannover, Germany. Contact
j...@openbsd.org.
I assume that if the wanted is still there form that chipset based
network card and you use the same chipset on yours that the support for
it is not as good as it could be?
Juts a thought, but I sure could well be way off as well.
Food for thought.
Best,
Daniel
