[dpdk-stable] patch 'test/hash: fix bucket size in perf test' has been queued to LTS release 17.11.5

[Yongseok Koh <yskoh@mellanox.com>]

Hi,

FYI, your patch has been queued to LTS release 17.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/01/18. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] test/hash: fix bucket size in perf test

[ upstream commit b772a15eb84ce616114880a20ad6ad91bb8970fc ]

The bucket size was changed from 4 to 8 but the corresponding
perf test was not changed accordingly.

In the test, the bucket size and number of buckets are used
to map to the underneath rte_hash structure. They are used
to test performance of two conditions: keys in primary
buckets only and keys in both primary and secondary buckets.

Although there is no functional issue with bucket size set
to 4, it mismatches the underneath rte_hash structure,
which may affect code readability and future extension.

Fixes: 58017c98ed53 ("hash: add vectorized comparison")
