[v6,2/3] app/testpmd: support ethdev rss level config
Checks
Commit Message
From: Kiran Kumar K <kirankumark@marvell.com>
Adding support to set RSS level from ethdev config.
level-inner is default and will set the RSS level to inner layers.
level-outer will set the RSS level to outer layers.
level-inner-outer will set the RSS level to both inner and outer
layers.

Thanks for this. But I think
You will have to add these options to cmd_help_long_parsed() under
port config all rss (all|....
level-outer|level-inner|level-inner-outer
Also cmd_config_rss.help_str needs to be extended to show the new options.
level-inner|inner-outer|level-inner-outer

You will have to add the new args to usage()
"--rss-ip | --rss-udp | --rss-outer | --rss-inner-outer | "
and add some description for the new options..
printf(" --rss-outer: set RSS hash level to outer");
printf(" --rss-inner-outer: set RSS hash level to default");
