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 setting is the DHCPEnabled property of ?

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 -

Do you see any issue here?
