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
