pouria added a parent revision: D56136: nd6: Remove goto and unused condition in prelist_update.

@ae, that's where I said we would probably have conflict over the reserved flags.

I didn't include the sys/netinet6/nd6_rtr.c part yet, so there is no dependency with other ndp revisions.
But I want to push them at once. (ofc, if approved)
