The BCM file seems to be missing all the queue configurations, this might cause problems. even CPU queue is not here, not sure if this is expected.

This is for pure lossy config using SDK defaults. Will need to check if explicit service pool configs are required.

No, this is a temporary branch. Once we get the final fix from BCM, this will be moved to main branch
