[dpdk-dev] [PATCH 2/3] app/test-pipeline: added cuckoo hash for benchmarking

[Sankar Chokkalingam]

This patch inclides cuckoo hash table into test-pipeline
This allows to benchmark the performance of the cuckoo hash table
The following key sizes are supported for cuckoo hash table
	8, 16, 32, 48, 64, 80, 96, 112 and 128.

The test-pipeline can be run using the following command
./app/testpipeline -c 0xe -n 4 -- -p 0xf --hash-cuckoo-8
