What needs to be validated

ieee-rs-fec is up to a F5 on a N9K-C93180YC-EX on 14.2. After upgrade to 5.2 port is down - with F1186 ieee-rs-fec is only supported certain switches - FX and up - https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/kb/b_Cisco_ACI_and_Forward_Error_Correction.html#Cisco_Reference.dita_5cef69b3-b7fa-4bde-ba60-38129c9e7d82

Why it needs to be validated

After upgrade links will be down on those nodes and may need to rollback or change the FEC if possible - some nodes only support ieee-rs-fec like F5 VELOS

Additional context

N/A

-EX only supports FC-FEC for 25G ports so if the port is still coming up on the older version it is a misconfiguration. https://www.cisco.com/c/en/us/products/collateral/switches/nexus-9000-series-switches/datasheet-c78-743149.html#Switchmodels

We can add an additional check for this.
