RTE_ETHDEV_QUEUE_STAT_CNTRS come from a limitation in Intel devices. They have limited number of registers to store the stats per queue. > Current default value is 16, which could likely be changed to 32 or 64 > without too much opposition.

Yes and? what is your issue exactly? with which device? Please explain the idea brought by your patch.
