	where do we use "routing advertisement" in the text?  I guess you mean
	"router advertisement".

	Neighbor Discovery Protocol (RFC2461) has two components and four
	ICMPv6 type #.
	- Neighbor Solicitation message - ARP request
	- Neighbor Advertisement message - ARP reply
	- Router Solicitation message - something like DHCP request
	- Router Advertisement message - something like DHCP reply

	rtsol(8) and rtsold(8) implements Router Solicitation sender logic.
	rtadvd(8) implements Router Advertisement message sender logic.

	so there's no confusion, we just picked different name.
