Subject: [PATCH] config/cn10k: align mempool elements to 128 bytes
Date: Mon, 13 Dec 2021 16:36:14 +0530	[thread overview]
Message-ID: <20211213110615.4458-1-pbhagavatula@marvell.com> (raw)

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

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.
Set RTE_MEMPOOL_ALIGN to 128 to force mempool buffers to be aligned
128 bytes.
