Ticket: CM-12478
Reviewed By: Roopa, Nikhil G
Roopa: "For vlan aware bridge, we don't support the port attributes under the
bridge. It was deliberately done when vlan aware bridge config was introduced
because people wanted to get rid of the legacy under the bridge way of decla-
-ring port attributes. It was supported for a bit for evorack...in limited
form. we should probably just warn the user about this."
