 The ch11 device in KLH10 for ITS, which was originally just a dummy
 inteface to keep ITS running, is now a functional Unibus Chaosnet
 device, which supports Chaosnet-on-Ethernet and Chaosnet-over-UDP.  
-It does not support SPY (promiscuous) mode, LUP (loopback), or
-broadcast, but ITS doesn't seem to use/need these.
