During the IPI bm provisioning process the deployment fails with the following error:

Error: could not inspect: could not inspect node, node is currently 'inspect failed' , last error was 'Redfish exception occurred. Error: Failed to get network interface information on node 995431b0-14c8-4aae-9733-e02b42da29ac: The attribute EthernetInterfaces is missing from the resource /redfish/v1/Systems/<redacted>'

Snippet from my install-config.yaml
      - name: ocp-test-2
        role: master
        bmc:
          address: redfish-virtualmedia://<redacted>/redfish/v1/Systems/<redacted>
          username: admin
          password: <redacted>
          disableCertificateVerification: True
        bootMACAddress: <redacted>

see above

Error: could not inspect: could not inspect node, node is currently 'inspect failed' , last error was 'Redfish exception occurred. Error: Failed to get network interface information on node 995431b0-14c8-4aae-9733-e02b42da29ac: The attribute EthernetInterfaces is missing from the resource /redfish/v1/Systems/<redacted>'

Because I already specified the bootMACAddress in the install-config.yaml I would like the installer to continue and don't fail when the Redfish API doesn't provide the EthernetInterfaces

The blades in this specific chassis don't have access to the NIC adapter.
Therefore they can't get the MAC address and populate this field in the Redfish API.
These blades are currently still selling and will need to be supported for another 5 years atleast.
Our new servers in the new chassis don't have this problem (X-Series).

Please keep the bootMACAddress as an optional field in the install-config.yaml to support these blades.
