> Without this patch, the number of queues per i40e VF is defined as 4 by
> CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VF=4 in config/common_base.
> It is fixed value determined in building time and can't be changed during run
> time.
> With this patch, the number of queues per i40e VF can be determinated during
> run time. For example, if the PCI address of an i40e PF is aaaa:bb.cc, with the
> EAL parameter -w aaaa:bb.cc,queue-num-per-vf=8 , the number of queues per
> VF created from this PF is 8.
> If there is no "queue-num-per-vf" setting in EAL parameters, it is 4 by default as
> before. And if the value after the "queue-num-per-vf"
> is invalid, it is set as 4 forcibly. The valid values include 1, 2, 4, 8, 16 .

> add description in i40e document
> fix the last member of valid_keys[] for rte_kvargs_parse( )
> add RTE_PMD_REGISTER_PARAM_STRING for this feature
> v7:
> use the macro instead of natural number
> correct git log message as the EAL parameter is only valid for PF
> v6:
> fix a small bug when detecting end character of strtoul
> v5:
> fix git log message and WARNING of coding stype
> v4:
> use rte_kvargs instead of pervious parsing function;
> use malloc/free instead of rte_zmalloc/rte_free.
> v3:
> fix WARNING of coding style issues from checkpatch@dpdk.org

BTW, I think release notes should be updated for your modifications.
