[PATCH v3 1/5] test/hash: fix bucket size in hash perf test

From: Yipeng Wang <hidden>
Date: 2018-09-26 19:59:21
Subsystem: the rest · Maintainer: Linus Torvalds

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")
