It just feels to me like if the only restriction in the driver is
regulatory, we shouldn't have it in the driver. That's what we have the
regulatory database for.

If there's some other (physical?) restriction in the driver, sure, maybe
it should have one there, but for pure regulatory I'm not sure I see it.

That's why the pointer here to ETSI feels so strange to me.

I'll need to see if we can remove it, but if we can I'll do that, and
otherwise I can just commit your patch but with a changed commit
message.

Note that I just sent my final pull request for the current kernel, so
this'll probably have to wait some time.
