Subject: [dpdk-dev] [PATCH 2/2] compressdev: add huffman encoding flags
Date: Wed, 27 Jun 2018 06:50:31 +0100	[thread overview]
Message-ID: <20180627055031.24394-2-pablo.de.lara.guarch@intel.com> (raw)
In-Reply-To: <20180627055031.24394-1-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.
