  log: "Pull up following revision(s) (requested by roy in ticket #845):\n\n\tsys/netinet6/nd6_nbr.c:
    revision 1.178\n\ninet6: nd6_na_input() now considers ln_state <= ND6_LLINFO_INCOMPLETE\n\nOtherwise
    if ln_state != ND6_LLINFO_INCOMPLETE and the is no lladdr\nand this message was
    solicited then ln_state is set to ND6_LLINFO_REACHABLE\nwhich could then cause
    a panic in nd6_resolve().\n\nIf ln_state > ND6_LLINFO_INCOMPLETE then it's assumed
    we have a lladdr.\nPotentially this could have been triggered by the introduction
    of\nND6_LLINFO_PURGE in nd6.c r1.143 but also by the re-introduction of\nND6_LLINFO_INCOMPLETE
    in nd6.c r1.263.\n\nDepending on the timing, it's technically possible to receive
    such\na message after the llentry is created with ND6_LLINFO_NOSTATE.\n"
