Mempool elements are by default aligned to CACHELINE_SIZE.
In CN10K cacheline size is 64B but the RoC requires buffers to be
aligned to 128B.
It would be good to say what the implication is in the commit message.
Set RTE_MEMPOOL_ALIGN to 128 to force mempool buffers to be aligned
128 bytes.
Fixes: 1b4c86a721c9 ("config/arm: add Marvell CN10K")
This is for backport? If so please add stable@ tag
