Hi Jiaxin,

Thank you very much for your info, Yes it works fine for manual configuration.

And also could you please provide steps to verify "Add DNS device path node" feature. 

Thanks,

Hi Karunakar,

According the UEFI Spec, the Ip4Config2DataTypeManualAddress, Ip4Config2DataTypeGateway and Ip4Config2DataTypeDnsServer configuration data are not allowed to set via SetData() if the policy is DHCP. So, the clear feature is only for the manual configuration. This is our design  purpose and also the reason why the feature is not apply to the Ip4Config2DataTypeInterfaceInfo/Ip4Config2DataTypePolicy.

Thanks,
Jiaxin
