You can trivially turn on 802.11n RX by enabling HT capabilities in the
driver (that'll give you 11n downlink transfers w/ AMPDU even).  That's
worked ever since I brought 11n support code into the tree (18 months
ago?).  11n transmit requires an 11n-aware rate control algorithm and as
far as I know noone is working on that.
