Performance: DPDK refactor
+ Rework BASH scripts (more code to python). + Move BASH into libraries. + Allows RDMA usage. + Fix 9000B tests. + Rename confusing l2fwd -> testpmd. + Fix suite setup. + Fix PCI whitelist to not accidentally pickup wrong interface. + Fix deprecated DPDK cli arguments. - MLX5 jumbo are disabled on NIC (i will increase separately). https://jenkins.fd.io/job/csit-dpdk-perf-verify-master-2n-clx/6/console (l3fwd still broken) - MLX5 IMIX seems to be some TRex issue with IMIX for mlx5 (i will handle separately) Signed-off-by: Peter Mikus <pmikus@cisco.com> Change-Id: I31d1b67305fa247cb5e1f57e739d3ef30dc1a04b
