	(not 3GPP/share related but: )

	with ND/NA on p2p ethernet it can be quite hard with some vendors
to clear DAD when an operator or customer configures the wrong IPv6 on
a p2p ethernet interface.  It can require bouncing the entier interface as
vendors haven't always had a way to clear DAD without bouncing the interface.

	If a link is point-to-point are there operations that should be
turned off, and should we define that list?  (perhaps DAD is one of them)
