From 5c51731ef45b84c2aab7b16d7daabc63ff2b21e2 Mon Sep 17 00:00:00 2001 From: Yulong Pei Date: Wed, 11 May 2022 05:11:28 +0000 Subject: Add gtpu flow offload test suite The implementation of GTPU offload rx is to use ip4_gtpu flow MARK action of NIC and vpp flow REDIRECT_TO_NODE and BUFFER_ADVANCE fuction to direct received gtpu flow to gtpu4-flow-input graph node, skipped ethernet-input, ip4-input, ip4-lookup, ip4-local, ip4-udp-lookup normal graph node processing. Verified on 3n-clx and Intel E810 NIC environment, single core with 64B packet, performance improve ~33% that compare with pure software way.
