From f0b85c9837b4f4f8d84df85a5763fcb52c12928e Mon Sep 17 00:00:00 2001 From: Jijiang Liu Date: Tue, 23 Jun 2015 00:40:58 +0800 Subject: [PATCH] examples/tep_term: add structures for VXLAN processing Add the common APIs of tunneling packet processing. We are trying to create a framework for tunneling packet processing, which includes - Tunnel port configuration - Tunnel setup - Tunnel destroying - Tunneling packet processing for Rx side - Tunneling packet processing for Tx side - Tunnel parameter processing Signed-off-by: Jijiang Liu Signed-off-by: Thomas Long --- examples/tep_termination/main.c | 1 + examples/tep_termination/vxlan_setup.h | 77 ++++++++++++++++++++++++++ 2 files changed, 78 insertions(+) create mode 100644 examples/tep_termination/vxlan_setup.h diff --git a/examples/tep_termination/main.c b/examples/tep_termination/main.c index 9154703082..618093a185 100644 --- a/examples/tep_termination/main.c +++ b/examples/tep_termination/main.c @@ -53,6 +53,7 @@ #include "main.h" #include "vxlan.h" +#include "vxlan_setup.h" /* the maximum number of external ports supported */ #define MAX_SUP_PORTS 1 diff --git a/examples/tep_termination/vxlan_setup.h b/examples/tep_termination/vxlan_setup.h new file mode 100644 index 0000000000..067987670e --- /dev/null +++ b/examples/tep_termination/vxlan_setup.h @@ -0,0 +1,77 @@ +/*- + * BSD LICENSE + * + * Copyright(c) 2010-2015 Intel Corporation.
