docs Drf Downstream Phy Dependencies

The summary of the Downstream Interface dependencies based on the constraints of docsDrfGroupDependencyEntry. A BIT position set to '1' indicates the PHY parameter belongs to a dependency group. A BIT position set to '0', indicates the PHY parameter does not belong to a dependency group. For Interfaces configured via DEPI this information is reflected in the DEPI session as DEPI TSID group dependencies. If this object value is the zero-length string, it indicates this interface is configurable via DEPI but no session is currently active.
