P4 resource keys with unique IDs

Reporters

• Georgios P. Katsikas

Description

Every P4 rule requires a unique resource key so as to appear on the WebUI

Sequence of actions that resulted in the bug

• 2 rule insertions with the same resource key (e.g., table)

Expected behaviour

• Every rule should follow a pattern, e.g., /tables/table/<table_name>[]
• This must be preserved by the person who loads the rules onto TFS as the code is unable to recover from a case when the resource keys are not unique. This may result in overwrites and "missing" rules in the UI (although properly installed in the dataplane)
