This enumerated value reports the DLDP-specific link status of a port, separate from its ordinary physical link state, valid only when the port's DLDP operating status is inactive, unidirectional, or bidirectional. Admins use it as a secondary check alongside hpnicfDldp2PortOperStatus, since it always returns unknown outside those specific operating states. A returned value of down(2) while the port's operating status is inactive confirms the physical link itself is down, not merely suspected unidirectional.
