Log Message:
Add David Hittner's DELQA/DEQNA Ethernet module for SIMH (PDP11 and
VAX).  Patches for the sim_ether module to support NetBSD, and a bug
fix to the XQ module from me (both patches sent to author).

Bump package revision to nb1.

NOTE: To work, this requires a patch to libpcap recently posted to
tech-net.
