Subject: [PATCH net-next 0/3] gro: Fixes for tunnels and GRO

This patch set addresses some issue related to tunneling and GRO:

- Ensure headers are pull into skb->head when putting 1st packet onto
  GRO list
- Fix remote checksum offload to properly deal with frag0 in GRO.
- Add support for GRO at VXLAN tunnel (call gro_cells)

Testing: Ran one netperf TCP_STREAM to highlight impact of different
configurations:

GUE
  Zero UDP checksum
    4628.42 MBps
  UDP checksums enabled
    6800.51 MBps
  UDP checksums and remote checksum offload
    7663.82 MBps
  UDP checksums and remote checksum offload using no-partial
    7287.25 MBps

VXLAN
  Zero UDP checksum
    4112.02
  UDP checksums enabled
    6785.80 MBps
  UDP checksums and remote checksum offload
    7075.56 MBps

  gro: Pull headers into skb head for 1st skb in gro list
  gro: Fix remcsum offload to deal with frags in GRO
  vxlan: GRO support at tunnel layer
