From: Lee Daly Date: Wed, 9 May 2018 16:14:26 +0000 (+0100) Subject: compress/isal: add skeleton ISA-L compression PMD X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=3c32e89f68e1f6edfd715b76925b95700e9cd4aa;p=dpdk.git compress/isal: add skeleton ISA-L compression PMD Adding basic skeleton of the ISA-L compression driver. No compression functionality, but lays the foundation for operations in the rest of the patchset. The ISA-L compression driver utilizes Intel's ISA-L compression library and compressdev API.
