I haven't really tested PCF at all, but yes, that should change managed
mode behavior. Anyway, I would be surprised if that RID would work in
Host AP mode.

I don't think current iwpriv would be the most convenient solution for
this. I don't link moving string parsing into the kernel driver and
setting variable length binary items does not fit will with iwpriv (I
think).

Take a look at Host AP snapshot.. I added utils/hostap_rid to make some
testing easier; it should also be usable from shell scripts if you need
to do something that is not directly supported in the driver.

Yes.. Although, I think I would prefer to add "real support" for all the
items that are considered useful in real life. hostap_rid should be fine
for testing and if something proves to be useful and requires persisten
RID configuration, it could be moved into driver code (with
iwpriv/whatever mechanism for configuration).
