James Prestwood d47e31954b auto-t: add test for HT/VHT rates
This is a VERY simple test for HT/VHT. Since there are so many potential
options in the IE this really just tests that drops in RSSI will cause
IWD to choose a different BSS, even if that means choosing HT over VHT,
or even basic rates over HT/VHT.
