Subject: [PATCH v6 10/10] test/hash: verify rte_jhash_1word/2words/3words
Date: Wed, 10 Jun 2015 16:25:27 +0100 [thread overview]
Message-ID: <1433949927-14767-11-git-send-email-pablo.de.lara.guarch@intel.com> (raw)
In-Reply-To: <1433949927-14767-1-git-send-email-pablo.de.lara.guarch@intel.com>
Added new test that verifies that rte_jhash_1words,
rte_jhash_2words and rte_jhash_3words return the same
values as rte_jhash.
Note that this patch has been added after the update
of the jhash function because these 3 functions did not
return the same values as rte_jhash before
Signed-off-by: Pablo de Lara <pablo.de.lara.guarch@intel.com>
