Hi, all We propose a new flow type, generic flow, in patch https://gerrit.fd.io/r/c/vpp/+/34802.
The generic flow is based on DDP (Dynamic Device Personalization) function and Parser Emulator module (which is supported in DPDK now and planned to be enabled in VPP native AVF). Using generic flow pattern, we do not need to create new packet and field type and offset in API parser (VAPI or VPP CLI) for every new protocols. We can create flows for any protocol immediately as long as supported by DDP. The generic flow can be used to support 5G related protocols in different scenarios, such as GTPU PDU-type and QFI. The input of generic flow are two binary strings. They may be not intuitive to users, so we will also upstream one tool named PacketForge later to help create a user friendly interface, using json configuration file or Scapy format command. The patch was sent several weeks ago and it passed all CI check. Could anyone help review? Thanks. Best Regards, Xu Ting
