2023-05-15packetforge: add option to show spec and mask onlyTing Xu4-40/+141
In some cases with Generic FLow, it is only required to show the pattern of spec and mask, but no need to add the flow. Therefore, add an option in packetforge so that users can show spec and mask only. Type: improvement Signed-off-by: Ting Xu <ting.xu@intel.com> Change-Id: I7b3040689eb82d0b58924712ee6fc9cfa0a42fa1

2022-09-20packetforge: add packetforge for generic flow to extrasTing Xu97-0/+4325
Add a new tool packetforge to extras. This tool is to support generic flow. Packetforge is a library to translate naming or json profile format flow pattern to the required input of generic flow, i.e. spec and mask. Using python script flow_create.py, it can add and enable a new flow rule for an interface via flow VAPI, and can delete an existed flow rule as well. Command examples are shown below. Json profile examples can be found in ./parsegraph/samples. Naming format input: python flow_create.py --add -p "mac()/ipv4(src=1.1.1.1,dst=2.2.2.2)/udp()" -a "redirect-to-queue 3" -i 1 python flow_create.py --del -i 1 -I 0 Json profile format input: python flow_create.py -f "./flow_rule_examples/mac_ipv4.json" -i 1 With this command, flow rule can be added or deleted, and the flow entry can be listed with "show flow entry" command in VPP CLI. Packetforge is based on a parsegraph. The parsegraph can be built by users. A Spec can be found in ./parsegraph as guidance. More details about packetforge are in README file.
