From: 6WIND <gru...@6wind.com>usage: dpdk-rss-flows.py [-h] [-s SPORT_RANGE] [-d DPORT_RANGE] [-r] [-k RSS_KEY] [-t RETA_SIZE] [-j] RX_QUEUES SRC DST Craft IP{v6}/{TCP/UDP} traffic flows that will evenly spread over a given number of RX queues according to the RSS algorithm. positional arguments: RX_QUEUES The number of RX queues to fill. SRC The source IP network/address. DST The destination IP network/address. options: -h, --help show this help message and exit -s SPORT_RANGE, --sport-range SPORT_RANGE The layer 4 (TCP/UDP) source port range. Can be a single fixed value or a range <start>-<end>. -d DPORT_RANGE, --dport-range DPORT_RANGE The layer 4 (TCP/UDP) destination port range. Can be a single fixed value or a range <start>-<end>. -r, --check-reverse-traffic The reversed traffic (source <-> dest) should also be evenly balanced in the queues. -k RSS_KEY, --rss-key RSS_KEY The random key byte-stream used to compute the RSS hash. This option supports either a supported driver name or the hex value of the key (default: intel). -t RETA_SIZE, --reta-size RETA_SIZE Size of the redirection table or "RETA" (default: 128). -j, --json Output in parseable JSON format.

I won't comment on the merits of inclusion of this into DPDK, but as far as code itself, this script makes me feel insecure about my Python skills! Can't really offer any constructive criticism, also learned a few new tricks.
So, for the code, Acked-by: Anatoly Burakov <anatoly.bura...@intel.com> -- Thanks, Anatoly
