@vmittal-msft , can you clarify what is the current behavior without this "default" BCM configuration specification?
Would it be up to the BRCM HWSKUs' decision on setting its own default if this is not specified?
@abdosi , Do we currently set this as part of the port attribute during port bring up? If we are not doing it currently, then having a "specified" default setting would be better than don't have it right? Otherwise, we have no way of knowing which BRCM based HWSKU default setting...

This property is needed as part of the BRCM fix for CPU to send LACP/BGP/LLDP packets on queue-7. In the absence of this property and sai fix, cpu will send packets to queue-0. for XGS platforms, we don't need this as cpu tx packets goes to queue-7.
