Hi,

The output is in line with the 802.11n specification, which calls all
of this stuff "HT".

I'll work with Eadler and others to improve the wireless documentation
and FAQ and I'll make sure there's a chapter on "802.11n", which
explains what HT (high throughput) is.

802.11ac is adding "VHT" (very high throughput) rates, so expect
ifconfig to grow vht information shortly.
