Subject: [dpdk-dev] [PATCH v2 2/6] baseband/turbo_sw: add support for CRC16
Date: Thu, 19 Aug 2021 14:10:06 -0700	[thread overview]
Message-ID: <1629407410-28822-3-git-send-email-nicolas.chautru@intel.com> (raw)
In-Reply-To: <1629407410-28822-1-git-send-email-nicolas.chautru@intel.com>

This is to support the case for operation
where CRC16 is to be appended or checked.
