> The name size of a rte_ring is RTE_MEMZONE_NAMESIZE with the value 32
> by default. When creating a HWS counter pool cache, the final string
> format was "RG_MLX5_HWS_CNT_POOL_%u_cache/%u" and it could support
> less than 1000 variants. For example, if the first %u representing
> port id is 100 and it will take all the available characters then the
> second %u for queues will be discarded. If there was more than one
> rule creation queue, the rte_ring could not be created.
> 
> By reducing the fixed character number and using hexadecimal format,
> the issue can be overcome with an assumption that not all the integer
> fields for queue index is used.
