From: Wisam Jaddo Date: Sun, 30 Aug 2020 11:15:38 +0000 (+0000) Subject: app/flow-perf: support raw encap/decap actions X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0c8f1f4ab90ef4acd63976de4a482891ed1d0aa4;p=dpdk.git app/flow-perf: support raw encap/decap actions Introduce raw-encap and raw-decap actions. The two actions are added in command line options, and for the data to encap or decap the user need to parse it within the command line. All values of raw-encap data is set to be fixed values. Usage example: --raw-encap=ether,ipv4,udp,vxlan Signed-off-by: Wisam Jaddo Acked-by: Alexander Kozyrev --- diff --git a/app/test-flow-perf/actions_gen.c b/app/test-flow-perf/actions_gen.c index 99e47bf786..3ae6059fb1 100644 --- a/app/test-flow-perf/actions_gen.c +++ b/app/test-flow-perf/actions_gen.c @@ -10,6 +10,8 @@ #include #include #include +#include +#include #include "actions_gen.h" #include "flow_gen.h" @@ -22,6 +24,23 @@ struct additional_para { uint16_t *queues;
