    inet6: nd6_na_input() now considers ln_state <= ND6_LLINFO_INCOMPLETE
    
    Otherwise if ln_state != ND6_LLINFO_INCOMPLETE and the is no lladdr
    and this message was solicited then ln_state is set to ND6_LLINFO_REACHABLE
    which then causes confusion elsewhere in the stack.
    If ln_state > ND6_LLINFO_INCOMPLETE then it's assumed we have a lladdr.
    
    Depending on the timing, it's technically possible to receive such
    a message after the llentry is created with ND6_LLINFO_NOSTATE.
    
    Taken from NetBSD.
