[Simh] vax under freebsd and ethernet.

[Mark Pizzolato]

Your physical setup seems OK.

However, there were "issues" with network support while running under
FreeBSD in simh v3.1-0.  Networking didn't work.

The issues have been addressed and useful functionality should be
available soon when v3.2 is released.  Note, the fix is NOT available
in any of the v3.2 preview releases that Bob has put together so far.

Before you get the release you can do a couple of the following
required external steps to get it working on your host:

1) Get the latest libpcap from www.tcpdump.org.
2) Unpack it, and patch the file pcap_bpf.c file by changing the
O_RDONLY to O_RDWR.
3) Build and install it with:
    # ./configure
    # make
    # make install

Once simh v3.2-0 is available, you should be good.
