The feature might work fine with many radios supported by this driver,
just not the asia-rf.

Seems the pci id for the asia-rf is same as other cards that do support
the feature, but hopefully the mtk folks can find some way to differentiate
the hardware automatically.

At least with user-space change, those wanting to use the feature on supported
hardware can do so with a config change in hostapd w/out having to hack yet another
out-of-tree patch into the driver.

Thanks,
Ben
