Standard way to use that would be using skb->priority
But I'm surprised you bother with TOS for multi queues at all. TOS
isn't a too important mechanism.
I would have thought the primary use case would be per CPU TX completion
interrupts. With that the queue should be selected based on
the the current CPU.
