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.
