I know the OpenBSD manual page says that bnx/bce can do full TCP offload;
I'm not sure I believe that (or that we'd want it if it actually could).

But do you know if it can do header splitting?  The newer Intel cards can,
and using it gives a significant performance boost under Linux by allowing
zero-copy receive to userspace.
