This is a clone of issue OCPBUGS-39438. The following is the description of the original issue:
—
Description of problem: If a customer applies ethtool configuration to the interface used in br-ex, that configuration will be dropped when br-ex is created. We need to read and apply the configuration from the interface to the phys0 connection profile, as described in https://issues.redhat.com/browse/RHEL-56741?focusedId=25465040&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-25465040

Version-Release number of selected component (if applicable): 4.16

How reproducible: Always

Steps to Reproduce:

1. Deploy a cluster with an NMState config that sets the ethtool.feature.esp-tx-csum-hw-offload field to "off"

2.

3.

Actual results: The ethtool setting is only applied to the interface profile which is disabled after configure-ovs runs

Expected results: The ethtool setting is present on the configure-ovs-created profile

Additional info:

Affected Platforms: VSphere. Probably baremetal too and possibly others.
