When the Root Port PS-PCIe core link is up, it is able to access the downstream endpoints.
However, the Data Link Layer Link Active status bit in Link Status Register still shows '0'.
In order for the Data Link Layer Active status bit in the Link Status Register to be set correctly, the "attr_link_cap_dll_link_active_reporting_cap" bit of the ATTR_35 (PCOE_ATTRIB) register at address 0xFD48008C should be set.
More information on this register can be found in (UG1087).
