From 33cd3fd52ffc20ed3247319384611f6bd0ef5ea7 Mon Sep 17 00:00:00 2001 From: Akhil Goyal Date: Wed, 20 Oct 2021 16:57:51 +0530 Subject: [PATCH] cryptodev: add device probing finish function Added a rte_cryptodev_pmd_probing_finish API which need to be called by the PMD after the device is initialized completely. This will set the fast path function pointers in the flat array for secondary process. For primary process, these are set in rte_cryptodev_start.
