Paolo Abeni says:

====================
net: extend indirect calls helper usage

This series applies the indirect calls helper introduced with commit
283c16a2 ("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.
