Yes, that's more straightforward.

My mistake. Thanks for pointing it out.

I thinks the name is self- explanatory, I also add some comments for them.  
As previous max_rx/tx_queues indicates how many queues available, these 
2 variables defines the queue ranges for VM usage.  
What kind of explanations you needs me to add?
