Subject: [dpdk-dev] [PATCH v4 2/2] app/test: add unit test for CRC computation
Date: Mon, 20 Mar 2017 19:29:40 +0000 [thread overview]
Message-ID: <1490038180-207288-3-git-send-email-jasvinder.singh@intel.com> (raw)
In-Reply-To: <1490038180-207288-1-git-send-email-jasvinder.singh@intel.com>
This patch provides a set of tests for verifying the functional
correctness of 16-bit and 32-bit CRC APIs.
