====================
net: gro: cleanups and fast path refinement

Current GRO stack has a 'fast path' for a subset of drivers,
users of napi_frags_skb().

With TCP zerocopy/direct uses, header split at receive is becoming
more important, and GRO fast path is disabled.

This series makes GRO (a bit) more efficient for almost all use cases.
