From: Haifei Luo Date: Wed, 12 May 2021 10:49:33 +0000 (+0300) Subject: app/testpmd: support action meter color X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c5c507100ea58e24f812401c77c66cdb9bceee36;p=dpdk.git app/testpmd: support action meter color Currently action RTE_FLOW_ACTION_TYPE_METER_COLOR is defined. Add the CLI for this action: color type (types) There are three types: green, yellow and red. Example for the new policy meter CLIs: add port meter policy 0 1 g_actions color type green / end y_actions color type yellow / end r_actions color type red / end In the above command, the action type is RTE_FLOW_ACTION_TYPE_METER_COLOR, the meter policy action list: green -> green, yellow -> yellow, red -> red.
