test/hash: fix bucket size in perf test
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") Cc: Signed-off-by: Yipeng Wang <> Acked-by: Bruce Richardson <> Reviewed-by: Honnappa Nagarahalli <>
