When many parallel flows are present and being received on the same
RX queue, GRO processing can become expensive because each incoming
frame must traverse the per-NAPI GRO list at each protocol layer
of GRO receive (eth --> ipv{4,6} --> tcp).
Use the already computed hash to chain these SKBs in a hash table
instead of a simple list.
The first patch makes the GRO list a true list_head.
The second patch implements the hash table.
This series patches basic testing and I added some diagnostics
to make sure we really were aggregating GRO frames :-)
