Foreman: 1.22.0
Katello: 3.12.0

Unable to join a machine using subscription manager with a bonded primary interface.

I get this error when using subscription-manager.

HTTP error (422 - Unknown): Validation failed: Attached to can’t be blank

I traced through the logs - I think it is an issue that it can’t tell what the slave ethernet devices are.

this is from the /var/log/foreman/production.log
