Goal

Let the cluster admin review which is the neighbor of each NIC of each node

User Stories

• As an Admin, I'd like to tell which of my nodes is connected to a specific switch, via which interface and which switch port, and how the port is configured on the switch. For example, I would like to find out if one of my nodes has its eno1 and eno2 swapped and wired to the wrong network.
• As an Admin, I would like to apply an NNCP stating "report LLDP on all interfaces", and then review the LLDP information reported on each NNS. This may be just applying

apiVersion: nmstate.io/v1
kind: NodeNetworkConfigurationPolicy
metadata: 
   name: enable-lldp-ethernets-up
spec: 
   capture: 
     ethernets: interfaces.type=="ethernet"
     ethernets-up: capture.ethernets | interfaces.state=="up"
     ethernets-up-lldp: capture.ethernets-up | interfaces.lldp.enabled:=true
  desiredState: 
     interfaces: '{{ capture.ethernets-up-lldp.interfaces }}'

Non-Requirements

• Test automation does not have to be done on the CNV side - upstream e2e tests are executed on OCP via https://github.com/openshift/kubernetes-nmstate

Notes

• NMState already reports lldp data if explicitly requested for each interface. This epic is about making it easy to use with kubernetes-nmstate.
• An interesting follow-up epic may be to have a conditional NNCP such as "create a bond on top of all NICs that are connected to VLAN 200".
