What needs to be validated

For a fault validation, describe the fault code and an example description message of the fault

For a config validation, describe the exact configuration to be validated
Need to make sure there are no in-use fabricHIfPol objects that have "speed" set to "auto".

For a bug validation, describe the bug ID (ex. CSCxx12345) and the brief description of the bug in the context of pre-upgrade validations.

Why it needs to be validated

Describe why it needs to be validated and what may happen if it's not validated.
If link speed "auto" is configured, many interfaces may not come up after a leaf stateless reboot (which happens during an upgrade). Using link speed "inherit" resolves this an is the best practice.
