Test creating NNCP connected to the host NIC over performnce lab - total of 6 nodes, one of the NNCP is stuck on ConfigurationProgressing, this is despite all the nodes appeared to be configured successfully.    

OCP 4.15.31 NMState operator 4.15.0    

    1. Create a 6 node cluster
    2. Deploy 400 NNCP
    

All NNCP in status SuccessfullyConfigured     

One NNCP stuck in status ConfigurationProgressing

All bridge are configured on the nodes :
