Description

It seems that when SBI connects to a P4 device that it had already connected in the past, it will not change the P4 program it has, even if instructed to do so.

Deployment environment

• Operating System (include version): all
• MicroK8s (include version and add-ons): microk8s v1.24.*
• TeraFlowSDN (include release/branch-name/commit-id): develop

TFS deployment settings

• list of components deployed: all cases
• particular configurations you applied: copying the P4 artifacts to the SBI Pod
• any other particularity you might find important: none

Sequence of actions that resulted in the bug

• Connect to a device using SBI and P4 handler.
• Disconnect from that device
• Clear everything in context and topology
• Change the P4 artifact files in the SBI pod
• Connect to the same device using SBI and P4 handler

Document the explicit error

• This is a not confirmed bug and should be investigated further, i.e.: it came up and was able to reproduce, but haven't investigated the source of the problem.

Expected behaviour

• When connecting to a device, we have previously connected too, the P4 program should change if explicitly requested.
