Re: [PATCH net-next v5 03/13] net: mana: swap queue sets in mana_set_channels

Build a replacement queue set before quiescing TX, then publish it and
retire the old set. Allocation failure preserves the running queues;
publication failure attempts rollback. If rollback also fails, close the
port and lower carrier, allowing a later administrative reopen.

Keep RX queue indices valid until retiring queues stop delivering. Order
the port-up store before TX ring reads to avoid a missed queue wakeup.

The temporary SQ/RQ peak is old + new. Later patches remove that peak for
channel-count changes; full per-queue rebuilds still require it.
