Cover letter [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.
