      Description

      When the Eip-Core is configured to not support the LLDP Data Table object (0x10A) - which is only possible when building a custom COM firmware - the LLDP Datastore attribute 4 (LLDP Management Object - 0x109) incorrectly reports that the "LLDP Data Table Object" is supported by setting bit 0.

      According to the expected behavior, bit 0 should be 0 in this case, indicating that the LLDP Data Table object is not available.

      Steps to Reproduce:

      1. Build a custom COM firmware without support for the LLDP Data Table object (0x10A).
      2. Observe the value of LLDP Datastore attribute 4 (0x109).
      3. Bit 0 is incorrectly set to 1 instead of 0.

      Expected Behavior:

      • Bit 0 of LLDP Datastore attribute 4 (0x109) should be 0 when the LLDP Data Table object (0x10A) is not supported.

      Actual Behavior:

      • Bit 0 is incorrectly set to 1, indicating support for the LLDP Data Table object despite it being unavailable.

      Impact:
      This incorrect reporting may lead to misinterpretation of LLDP capabilities and potential issues with network management tools relying on this attribute.

      Suggested Fix:
      Ensure that bit 0 of LLDP Datastore attribute 4 (0x109) is correctly set to 0 when the LLDP Data Table object (0x10A) is not included in the build.
