Right now the `lldp` facts has `{'eno1': {'vlan': 'vlan-1001', 'neighbor': 'asw2-a-eqiad', 'port': 'ge-4/0/22'}}`
Or
```{'ens3f1np1': {'vlan': 'vlan-1106', 'neighbor': 'cloudsw1-c8-eqiad.mgmt.eqiad.wmnet', 'port': 'xe-0/0/47'}, 'ens3f0np0': {'vlan': 'vlan-1118', 'neighbor': 'cloudsw1-c8-eqiad.mgmt.eqiad.wmnet', 'port': 'xe-0/0/27'}}```
While lldpcli also show:
```[lldpcli] # show neighbors
[...]
PortDescr: bast3004:enp175s0f0 {#20052}```
This would be useful to get the cable ID `{#xxxx}` of a given switch<->host cable for T262899
Additionally, the MTU is exposed like:
`MFS: 9192`
Which would be great to get as well.
Last, the vlan is exposed as `VLAN: 100, pvid: yes vlan-100`
So it would be better to strip the `vlan-` prefix, and use directly the vlan ID (`100`).
One open question is: should we directly expose the cable ID as well as fact, or only the PortDescr?
