* sys/netinet6/nd6.c: better support for proxy NDP (per NA entry,   just like arp -s).  routing entry marked with RTF_ANNONUCE   (= RTF_PROTO2) will get announced by proxy ND.  on ND table, proxy   NDP entry will stay as permanent/reachable entry.

  To use this stuff, you need to backout bbn changes in rtsock.c.
  otherwise ndp -s will not work and you can not set proxy ND entry.

  TODO:
  - proxy NA delay on output (RFC2461 7.2.8)
  - anycast NA delay on output (RFC2461 7.2.7)
* */usr.sbin/ndp: proxy ND support (ndp -s has "proxy" keyword added).

  TODO: proxy ND for global address X, where X is outside of prefixes
  assigned to the interface we would do proxy ND.  currently we try to
  grab link-layer information from RTM_GET.  so if X is outside of
  configured prefixes, we can't configure X for proxy NDing, or static
  ND entry.  we may need to explicitly pass "interface" information
  to ndp -s.
