I would be much more likely to accept a change that would disable this

future, this new configuration option in hostapd could then be change to
default to having this capability enabled or even better, remove that
configuration parameter completely once there are no known issues in
commonly used kernel versions.

This was a pretty recent driver capability, arguably it should just be
disabled in the driver (CC stable) and then we don't need to have these
discussions in userspace ...

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
