[Simh] MicroVax 3900 Networking on a Macbook Air

[Johnny Billquist]

The problem is that WiFi just isn't ethernet, and you will never get it 
to work good trying to behave like it is. Unfortunately...

libpcap don't change that. (Without libpcap you can never get networking 
in SimH to work, but even with it, you still need a network medium that 
behaves like ethernet.)
