LLDP packets processed by ironic_python_agent.netutils break node network connectivity when doing ZTP

      Description of problem:

      I am deploying a OCP (4.12) cluster using ZTP (ACM/gitops/assisted-service under the hood/ HUB cluster at 4.13). There we provide the network configuration in nmstate. The installation fails at the very beginning because the ironic_python_agent.netutils adds some vlans which break the connectivity and those vlans seem to be coming from LLDP.

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

       

      How reproducible:

      (very hard) Have LLDP configured in the switch (https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/concept/layer-2-services-lldp-overview.html) and overwrite the desired nmstate (e.g. have a vlan in the interface that originally is in the bond)

      Actual results:

       

      Expected results:

       

      Additional info:

      We expect to be able to disable from ZTP down to ironic config because it might not be possible/desired to disable it in the switch fabric
