Subject: select(2)+DHV-11+non_network_kernel (#86)
Index:	sys/pdpuba/dhv.c 2.11BSD

Description:
	In a non-networked kernel the select() call will not work with
	a DHV-11 channel.

Repeat-By:
	Build a non-networking kernel on a system with a DHV-11.  Note
	that the select() system call doesn't work.

Fix:
	When the DHV-11 driver was moved from the OTHERS/ directory to
	pdpuba/ directory (update #42, Dec 1991) the extraneous UCB_NET 
	reference was not deleted (2.9BSD conditionalized 'select' on UCB_NET,
	beginning with 2.10BSD select() does not require networking to be
	present).

	Apply the following update to pdpuba/dhv.c
