Early on there was bugs in stock firmware for how it did VHT160
vs how the driver thought it did.  I ended up fixing the CT firmware
to match closer to how the driver wanted it done at the time, but
I think that the driver has since changed.

I have not had time (nor much interest) to try to make my firmware work again with stock
driver for VHT160.

Either way, VHT160 is almost completely worthless because it can only
do 2x2 at VHT160, which is no faster than VHT80 at 4x4 but uses twice
as much bandwidth.

Thanks,
Ben
