Subject: [dpdk-dev] [PATCH v3 4/4] compressdev: add huffman encoding flags
Date: Wed, 4 Jul 2018 15:10:37 +0100 [thread overview]
Message-ID: <20180704141037.44021-4-pablo.de.lara.guarch@intel.com> (raw)
In-Reply-To: <20180704141037.44021-1-pablo.de.lara.guarch@intel.com>
Added Huffman fixed and dynamic encoding feature flags,
so an application can query if a device supports
these two types, when performing DEFLATE compression.
