It was subsumed into the forthcoming 802.11n specification, and it  
only works for unicast transmissions.  This implies that RA  
announcements could be filtered, and router discovery multicasts  
could conceivably be screened and not forwarded past the AP at the  
802.11 layer.  However, DLS could still be used to send RA unicasts  
to attack hosts willing to accept them.
