[dpdk-dev] [PATCH v1 1/1] mempool/octeontx2: remove minimum chunck size limitation

[vattunuru]

From: Vamsi Attunuru <vattunuru@marvell.com>

Memory required for the mempool objects need not be physically
contiguous on octeontx2's HW, mempool pmd supports the minimum chunk
size set by the default handler. Hence discarding the limitation set
by the pmd on the min_chunk_size value.

This patch needs to go through to master repo based on MAINTAINERS
file. Changing the "Delegate to" to Thomas in patchwork.
