From 3b622711bcdf51d6f4c160e688f3d9c70c9f039e Mon Sep 17 00:00:00 2001 From: Salem Sol Date: Wed, 7 Apr 2021 14:50:51 +0300 Subject: [PATCH] app/testpmd: support NVGRE encap as sample action Add support for rte_flow_action_nvge_encap as a sample action. The example of test-pmd command: 1. set nvgre ip-version ... tni ... ip-src ... ip-dst ... set raw_encap 1 eth src... / ipv4... /... set sample_actions 2 nvgre / port_id id 0 / end flow create 0 ... pattern eth / end actions sample ratio 1 index 2 / raw_encap index 1 / port_id id 0... The flow will result in all the matched egress packets will be encapsulated and sent to wire, and also mirrored the packets using NVGRE encapsulation data and sent to wire.
