Those which are on-link, of course.

Do you really think off-link prefixes are to be saved? Prefix in use is onlink
by defintion, so just return 1 in these bit and ignore off-link prefixes
completely, they are meaningless, are not they?

Well, if SNMP is going to be used as a tool to snoop ndisc promiscuously
(which seems to be the case if it shows inforrmation about offlink prefixes),
then it is definitely not a kernel task.
