[dpdk-dev] [PATCH v6 03/10] test/hash: update key size range and initial values for testing

Previous key sizes used for testing did not have much purpose.
This patch substitutes them with some more meaninful
(standard multiple of 2 key sizes, plus IPv4/v6 tuple and others)
Also an arbitrary initial value has been added to increase
the test coverage, and RTE_DIM macro is used to iterate the loops.
