FreeBSD 11-CURRENT - WLAN TMA Support

[Seinstein Meinstein]

Hello All,
I would like to know if the latest FreeBSD version has support for the following:
1. Fully functional TDMA (Time Division Multiple Access) in the 802.11 wireless driver code. 2. What protocol version does it support? Specifically I am looking for the latest 802.11ac/802.11n protocol support. 3. Can the driver code be fully cross compiled for any platform (ARM, PowerPC, etc.?)4. Where can I get the tar ball (tar.gz?). Please provide pointers, I can only find web access to the files. GitHub project will also help. 
Thanks very much in advance,Sridharan.
