From: Pablo de Lara Date: Fri, 6 Jul 2018 05:28:01 +0000 (+0100) Subject: compressdev: add huffman encoding flags X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0260571c99e08966dd8eeefc2e44c33b8a14f626;p=dpdk.git compressdev: add huffman encoding flags Added Huffman fixed and dynamic encoding feature flags, so an application can query if a device supports these two types, when performing DEFLATE compression.
