Subject: [PATCH net-next 0/4] net: extend indirect calls helper usage

This series applies the indirect calls helper introduced with commit 
283c16a2dfd3 ("indirect call wrappers: helpers to speed-up indirect 
calls of builtin") to more hooks inside the network stack.

Overall this avoids up to 4 indirect calls for each RX packets,
giving small but measurable gain TCP_RR workloads and 5% under UDP
flood.

Paolo Abeni (4):
  net: use indirect calls helpers for ptype hook
  net: use indirect calls helpers for L3 handler hooks
  net: use indirect calls helpers at early demux stage
  net: use indirect calls helpers at the socket layer
