From a1f20f1abc15d701ef076a3953c0bdf2523e45fa Mon Sep 17 00:00:00 2001 From: Salem Sol Date: Wed, 7 Apr 2021 14:50:14 +0300 Subject: [PATCH] app/testpmd: support VXLAN encap as sample action Add support for rte_flow_action_vxlan_encap as a sample action. The example of test-pmd command: 1. set vxlan ip-version ... vni ... udp-src ... set raw_encap 1 eth src.../ ipv4.../... set sample_actions 2 vxlan_encap / 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 VXLAN encapsulation data and sent to wire.
