No, I don't think we would need to move away from our existing method:
spin_lock_irqsave(&mac->lock, flags);
if (mac->updating_rts_rate == 0 && mac->updating_basic_rates == 0)
netif_wake_queue(mac->netdev);
spin_unlock_irqrestore(&mac->lock, flags);
That said, it is in some ways comparable to refcounting without a
counter: if both flags are set to 0, the above code is guaranteed to be
executed twice (each time after one flag is toggled)
