If i am getting it correctly , the current changes which were made to 
the phosphor-settings-manager should be good enough to handle all the 
scenarios.

In my last email i mentioned that ===>>

When the Ethernet interface set to be DHCP enabled ( by setting the Bios 
attribute DHCPEnabled = true via redfish), the IPAddress, SubnetMask and 
Gateway along with the Origin property will not be Bios settings. Here 
the user will be setting the DHCPEnabled property.
However in the case of Static IP configuration(IPAddress, SubnetMask and 
Gateway) they will become bios setting.

Currently we are using the xyz.openbmc_project.Network.IP and this 
interface is being implemented by settings object - 
https://gerrit.openbmc-project.xyz/#/c/openbmc/meta-ibm/+/30424/

Do you see any issues here?
