bbc7bad132 ETHER: Give platform appropriate advice when no pcap devices are available 
Windows needs Npcap/Winpcap, *nix systems usually need to run as root.

21f2aeb453 makefile: Update makefile sel32 definitions to use {} instead of () 
This makes this simulator identical in form to all others and simplifies
alternate parsing/transformation of the makefile to alternate forms (cmake).

16943b4582 QBus VAX and PDP11: Add support for HDLC framing to DUP11/DPV11 
This commit extends the existing DUP11/DPV11 support to add support for HDLC framing. There
is no requirement to support bit/byte stuffing, so the aim is simply to encapsulate/decapsulate
the datalink frame provided by the host driver.

DDCMP has been regression tested on VMS, RSX and TOPS20, and the HDLC mode was developed
and tested with VAX/VMS DECnet Phase V, only using the HDLC datalink implementation.

In theory this support is sufficient to allow Phase IV/V P.S.I and even VMS/SNA to be used,
but these remain to be demonstrated.
