From: Liad Kaufman <[email protected]> When sending the SCD_QUEUE_CONFIG command, the queue is associated to a specific TID. If later there is a need to use this TID on a different queue instead, it first needs to be unassociated from the first queue.
Keep track for every queue what TID is associated with it.
