Yes, but uAPI is forever. We will have to live with those domain
attributes duplicated on each port. Presumably these port attributes
will never support a SET operation, since the set should be towards
the domain? The uAPI does not inspire confidence. If we need more
drivers to define a common API maybe a local sysfs API in the driver
will do?
