iwlwifi support Master Mode: 

http://en.wikipedia.org/wiki/Comparison_of_open-source_wireless_drivers

but I try and it seems to not work 
------------------------
iw phy phy0 info | less
....
        Supported interface modes:
                 * IBSS
                 * managed
                 * monitor
        software interface modes (can always be added):
                 * monitor
.....


------------------------

even if the output of iw command show something about 
AP and AP/VLAN for TX and RX frames:
