This series collects a couple of small optimizations for the GRO engine,
reducing slightly the number of cycles for dev_gro_receive().
The delta is within noise range in tput tests, but with big TCP coming
every cycle saved from the GRO engine will count - I hope ;)

v1 -> v2:
 - a few cleanup suggested from Alexander(s)
 - moved away the more controversial 3rd patch

Paolo Abeni (2):
  net: gro: avoid re-computing truesize twice on recycle
  net: gro: minor optimization for dev_gro_receive()
