Disabling a port leaves its queued frames holding buffers charged to the admission and shared groups, so every other port is admitted against a smaller pool. On port_disable, stop each unicast and multicast queue's enqueue and dequeue, flush it through FLUSH_CFG and wait for completion, one queue at a time with the QM clock gate dropped around the pass. The gates stay closed until port_enable, and the CPU port is skipped. On IPQ8074 a full queue drains to empty when its port goes down and fills again once the port is back up.
