FreeBSD 802.11n: aiee

I've been toying with getting 802.11n working on these atheros AR9160's.

I've got somewhat working 802.11n on the receive side using my public HAL, up to MCS15. But it (currently) isn't implementing AMPDU (datagram aggregation) which is done in software, so it isn't much faster than legacy mode.

But it -does- work - in 20mhz 11ng mode:

root@OpenWrt:~# iw dev wlan0 station dump
Station 00:15:6d:84:05:52 (on wlan0)
inactive time: 0 ms
rx bytes: 41144714
rx packets: 475307
tx bytes: 1059470517
tx packets: 692698
signal: -50 dBm
tx bitrate: 130.0 MBit/s MCS 15
