    netinet6: Improve flexibility of receiving Router Advertisement
    
    Convert the sysctl 'net.inet6.ip6.accept_rtadv' to be the default value
    of the per-interface flag 'ND6_IFF_ACCEPT_RTADV', making it no longer a
    global knob.  Now the receiving RA is allowed if ip6_forwarding==0 *and*
    'ND6_IFF_ACCEPT_RTADV' is set on that interface.
    
    ndp(8) already supports to toggle the 'ND6_IFF_ACCEPT_RTADV' flag via
    the 'accept_rtadv' option.
    
    Derived from FreeBSD.
