This patch series introduces hairpin memory configuration options proposed in http://patches.dpdk.org/project/dpdk/patch/20220811120530.191683-1-dsosnow...@nvidia.com/ for Rx and Tx hairpin queues. It also implements handling of these options in mlx5 PMD and allows to use new hairpin options in testpmd (through `--hairpin-mode` option) and flow-perf (through `--hairpin-conf` option).
