No, it's the other way around... I'd rather use the pcn driver, since I
get dramatically better performance using it.  My problem is that I'm
seeing a lot of collisions with both the le and pcn driver, which may or
may not be an OpenBSD problem.

The other machines on the same ESX host don't seem to show any problems,
but this is the only OpenBSD guest.
