[dpdk-dev] [PATCH v5 04/10] test/hash: change order of loops in hash function tests

[Pablo de Lara]

In order to see more clearly the performance difference
between different hash functions, order of the loops
have been changed, so it iterates first through initial values,
then key sizes and then the hash functions.
