[Simh] Broken ethernet code?

[pgaray at bigfoot.com]

I failed to be able to use the ethernet on a build earlier
this year on FreeBSD 4.11 (or 4.10). I am sorry I did not note
what exacly happened and I no longer have that install - at
the time I thought that I'll use the 5.x branch (thinking that
the new pcap was propbaly requiring the new kernel) but never
got to it. My recollection was that after the first or the
first few packets it failed (i am sorry, do not recall how).
