netX9x2 - Update of DPM IO Data not working properly

For the netX9x2 (GenAP V2) target, the update of DPM IO data is not working as expected.

The consumer update mechanism should be triggered by the protocol stack (Device Controlled Mode).
Currently, the behavior follows the Host Controlled Mode, as implemented for the other targets.

In GCI V2, the provider data update mechanism differs from V1. The fnProviderDataUpdateDone has been replaced by the callback function fnProviderDataUpdate that must be explicitly called by PNDIF to adopt the provider data from DM and swap the triple buffer.
