Subject: [PATCH] app/testpmd: support updating flow rule actions
Date: Fri, 26 Jan 2024 14:21:42 +0100 [thread overview]
Message-ID: <20240126132142.2649250-1-okl-plv@napatech.com> (raw)
"flow actions_update" updates a flow rule specified by a rule ID with a
new action list by making a call to "rte_flow_actions_update()":
flow actions_update {port_id} {rule_id}
actions {action} [/ {action} [...]] / end [user_id]
Creating, updating and destroying a flow rule:
testpmd> flow create 0 group 1 pattern eth / end actions drop / end
Flow rule #0 created
testpmd> flow actions_update 0 0 actions queue index 1 / end
Flow rule #0 updated with new actions
testpmd> flow destroy 0 rule 0
Flow rule #0 destroyed
