With 1.2 release nearing completion I went back to see what's going on
with this wotk, and it looks like I forgot to reply to this question.
Sorry.

I think we need a way for device to be notified about capabilities
of the driver. Current query only works the other way.

I would like us to move to add another group of feature bits intended
for the management purposes. Maybe just 32 bit, or maybe "extended
features" with a selector and length like mmio and ccw already do,
up to you.

This will replace functionality of the query capabilities command and
have the advantage of also notifying device about capabilities of the
driver.
