Hi Helin,

Is the layout of the queues and how CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_PF
affects them documented? 

I'm wondering if I increase CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_PF to more
than 64 queue, will they be contiguous? For example, if I increase to 128 
will I be able to use queues 0-127, or there will there be gaps for queues
reserved for VMDQ etc.

Kevin.
