From: Lee Daly Date: Wed, 9 May 2018 16:14:27 +0000 (+0100) Subject: compress/isal: add device init and de-init X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=490e725b95b2;p=dpdk.git compress/isal: add device init and de-init This patch adds device initialization functionality such as probe and create, also adding deinitialize functionality. Dynamic logging component also added.
