This includes the following libraries 1. ACL library 2. SIP 3. FTP 4. Connection tracker 5. L2l3 stack - Interface Manager - ARP & ICMPv4 - ND & ICMPv6 and other common libraries needed for ip pipeline framework Change-Id: I117690b6b63fbcd76974cd7274518484e60980ab Signed-off-by: Vishwesh M Rudramuni [Push patch to gerrit] Signed-off-by: Deepak S --- common/vnf_common/vnf_common.h | 200 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 200 insertions(+) create mode 100644 common/vnf_common/vnf_common.h (limited to 'common/vnf_common/vnf_common.h') diff --git a/common/vnf_common/vnf_common.h b/common/vnf_common/vnf_common.h new file mode 100644 index 00000000..a6b1aaa2 --- /dev/null +++ b/common/vnf_common/vnf_common.h @@ -0,0 +1,200 @@ +/* +// Copyright (c) 2017 Intel Corporation +// +// Licensed under the Apache License, Version 2.0 (the "License");
