From: Akhil Goyal Date: Mon, 3 Jul 2017 12:31:36 +0000 (+0530) Subject: crypto/dpaa2_sec: add per dev mempool to store FLE X-Git-Tag: spdx-start~2671 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b23d4e898adecb596f5483d12f7224cc4114c374;p=dpdk.git crypto/dpaa2_sec: add per dev mempool to store FLE rte_malloc uses common memory area for all cores. Now rte_malloc are replaced by per device mempool to allocate space for FLE. This removes contention and improves performance.
