This is very preliminary and mostly enough for me (with other patches) to work on VHT support. It adds: * VHT20, VHT40 and VHT80 regulatory/band awareness * VHT20, VHT40 and VHT80 channel configuration / population * Parses vht channel specifications (eg ifconfig wlan0 create wlandev athp0 wlanmode monitor channel 36:vht/80) * Configuration of VHT, VHT40, VHT80, VHT80+80, VHT160 channel width (IEEE80211_FVHT_VHT* flags in net80211) TODO: * No VHT80+80 or VHT160 channels yet - I don't yet have hardware, and I'm not yet sure how to support/populate VHT80+80 channels. * No, I won't update the manpage until this is "more done", lest someone tries using vht and gets upset with me. * No, I won't commit the regulatory database I'm testing with, so you'll just end up with no VHT channels ever populated. Which is good, as there isn't an 11ac driver in-tree yet to try it with.
