To get the changes in:
65b32f801b ("uapi: move IPPROTO_L2TP to in.h")
5854a09b49 ("net/ipv4: Use __DECLARE_FLEX_ARRAY() helper")
That ends up automatically adding the new IPPROTO_L2TP to the socket

Now 'perf trace' will decode that 115 into "L2TP" and it will also be
possible to use it in tracepoint filter expressions.
