pfcp: add PFCP module Packet Forwarding Control Protocol (PFCP) is a 3GPP Protocol used between the control plane and the user plane function. It is specified in TS 29.244[1]. Note that this module is not designed to support this Protocol in the kernel space. There is no support for parsing any PFCP messages. There is no API that could be used by any userspace daemon. Basically it does not support PFCP. This protocol is sophisticated and there is no need for implementing it in the kernel. The purpose of this module is to allow users to setup software and hardware offload of PFCP packets using tc tool. When user requests to create a PFCP device, a new socket is created. The socket is set up with port number 8805 which is specific for PFCP [29.244 4.2.2]. This allow to receive PFCP request messages, response messages use other ports. Note that only one PFCP netdev can be created. Only IPv4 is supported at this time.
