[net-next,0/3] gro: some minor optimization

Message

This series collects a few small optimization for the GRO engine.
I measure a 10% performance improvements in micro-benchmarks
around dev_gro_receive(), but deltas are within noise range in tput
tests.

Still with big TCP coming every cycle saved from the GRO engine will
count - I hope ;)

The only change from the RFC is in patch 2, as per Alexander feedback

Paolo Abeni (3):
  net: gro: avoid re-computing truesize twice on recycle
  net: gro: minor optimization for dev_gro_receive()
  net: gro: register gso and gro offload on separate lists
