ConditionalRequirements related to Manager EthernetInterfaceCollection for skipping logical instance like usb0

[plmanik]

Hi,
As per https://github.com/opencomputeproject/HWMgmt-OCP-Profiles/blob/master/HWMgmt/OCPBaselineHardwareManagement.v1_1_0.json

HostName": {
	"ReadRequirement": "Recommended",
	"ConditionalRequirements": [{
		"SubordinateToResource": ["Manager", "EthernetInterfaceCollection"],
		"ReadRequirement": "Mandatory",
		"WriteRequirement": "Mandatory"
	}]

Based on ConditionalRequirements, WriteRequirement is verified for eth0(physical instance), usb0(Logical instance for Host interface communication between BMC and Host) in Manager ethernetinterface instance. In case of usb0(Logical instance for Host interface communication between BMC and Host) it's not required to support changing HostName, FQDN, IPv4Addresses#0, NameServers since it's going to be same as physical instance(eth0) in Manager resource.
Chances for some Physical instance also to restrict patch. Is it possible to skip WriteRequirement for logical interface by using use case or anyof comparison to make sure to change one instance in Manager ethernetinterface collection?

@mraineri @jautor Please add your inputs based on schema for skipping WriteRequirement for logical ethernetinterface instance like usb0 or we can accept patch on usb0, reflect the values in eth0, usb0

Thanks,
Mani

Valid issue. Need to decide how to solve. Use Supported?

Can we use URIs to handle this situation

"EthernetInterface": {
            "ReadRequirement": "Mandatory",
            "URIs": [
                "/redfish/v1/Managers/{ManagerId}/EthernetInterfaces/{EthernetInterfaceId}"
            ],

Thanks,
Mani

The URI won't work because other NICs on the Manager also need to be tested. Decision to use "Supported".

Will also modify the Profile spec and/or model to handle this case.
