This will provide the means for setting or displaying the adapters, domains and control domains assigned to the vfio-ap mediated device in a single operation. This sysfs attribute is comprised of three masks: One for adapters, one for domains, and one for control domains. This attribute is intended to be used by mdevctl to query a vfio-ap mediated device's state. Signed-off-by: Jason J.
