      * Previously, bonds that were configured in `active-backup` mode would have IPsec Encapsulating Security Payload (ESP) offload active even if underlying links did not support ESP offload. This caused IPsec associations to fail. With this release, ESP offload is disabled for bonds so that IPsec associations pass. (link:https://issues.redhat.com/browse/OCPBUGS-39438[*OCPBUGS-39438*])

      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.
