[dpdk-dev] [PATCH v3 6/6] app/testpmd: show the hash key size

[Helin Zhang <helin.zhang@intel.com>]

As querying hash key size in byte was supported, it can be shown
in testpmd after getting the device information if not zero.

v2 changes:
* Disabled the code changes by default, to avoid breaking ABI compatibility.

v3 changes:
* As newly added element was put to a padding space, it will not break ABI
  compatibility, and no need to disable the code changes by default.
