Subject: [dpdk-dev] [PATCH v4 04/10] compress/isal: add private xform related ops
Date: Sat, 28 Apr 2018 00:38:27 +0100 [thread overview]
Message-ID: <1524872313-196340-5-git-send-email-lee.daly@intel.com> (raw)
In-Reply-To: <1524872313-196340-1-git-send-email-lee.daly@intel.com>
This patch creates, configures and frees the private xform, taking the
applications xform and using it to populate the PMDs own private xform
with the information which will be required for the compress/decompress
functions. This information includes the level, algorithm,
type of huffman code, type of checksum etc.
