From: Ashish Gupta Date: Tue, 24 Jul 2018 15:05:32 +0000 (+0530) Subject: compress/zlib: introduce zlib PMD X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0c4e4c16b004;p=dpdk.git compress/zlib: introduce zlib PMD Add initial PMD setup routines in compressdev framework. ZLIB PMD appears as virtual compression device. User would need to install zlib prior to enabling this PMD.
