Ensure DDP Package is Loading Properly
Ensure that the driver reports the presence and successful load of the Dynamic Device Personalization (DDP) package file. In the event of a DDP package load error, the device defaults to safe mode and many performance features are unavailable.
The DDP package was successfully loaded: ICE OS Default Package version X.X.X.X
If there are errors related to loading the DDP package, it will cause performance issues. As a workaround to resolve DDP load issues, try to unload and reload the ice driver. For troubleshooting steps, refer to the Intel® Ethernet Controller E810 Dynamic Device Personalization (DDP) Technology Guide (#617015)
