> Subject: [PATCH] app/testpmd: Optimize membuf pool allocation
>
> By default, testpmd will create membuf pool for all NUMA nodes and ignore
> EAL configuration.
>
> Count the number of available NUMA according to EAL core mask or core list
> configuration. Optimized by only creating membuf pool for those nodes.

> Fixes: d5aeab6542f ("app/testpmd: fix mempool creation by socket id")
