Subject: [PATCH v2 net-next 0/4] 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
    
v2:
  - Drop "gro: Pull headers into skb head for 1st skb in gro list"
    from patch set
  - In vxlan_remcsum and gue_remcsum return immediately if remcsum
    processing was already done
  - Add gro callbacks for sit offload
  - Use WARN_ON_ONCE if we get a GUE protocol that does not have
    GRO offload support


Tom Herbert (4):
  gro: Fix remcsum offload to deal with frags in GRO
  vxlan: GRO support at tunnel layer
  ipv6: Add gro functions to sit_offloads
  fou: Do WARN_ON_ONCE in gue_gro_receive for bad proto callbacks
