I would like to have the other request_queue limitations exposed
here, too.
Most notably we're missing the maximum size of an individual segment
and the maximum size of the overall I/O request.
The virtio transport does not put any limit, as far as I know.
Virtio doesn't, but the underlying device/driver might.
And if we don't expose these values we cannot format the request correctly.
These limits should be per target/LUN, so it seems like material for
another controlq command when the need arises. For now, I'd really
prefer to have the spec match the implementation (plus a few SAM
bogosities).
