Its value depends on hh3cCBQoSApplyObjectType.
It represents the value of VPI/VCI, of which high 16-bits
is VPI and low 16-bits is VCI, when hh3cCBQoSApplyObjectType
is atmPvc(3).
It represents the value of data link connection identifier
in FR network, when hh3cCBQoSApplyObjectType is frDlci(4).
Otherwise the value is '0xFFFFFFFF'.
