[iproute2-next,v3,1/2] ip: PFCP device support

Commit Message

Wojciech Drewek April 22, 2024, 12:05 p.m. UTC

Packet Forwarding Control Protocol is a 3GPP Protocol defined in
TS 29.244 [1]. Add support for PFCP device type in ip link.
It is capable of receiving PFCP messages and extracting its
metadata (session ID).

Its only purpose is to be used together with tc flower to create
SW/HW filters.

PFCP module does not take any netlink attributes so there is no
need to parse any args. Add new sections to the man to let the
user know about new device type.
