vxlan: GRO support at tunnel layer
Add calls to gro_cells infrastructure to do GRO when receiving on a tunnel.
Testing:
Ran 200 netperf TCP_STREAM instance
- With fix (GRO enabled on VXLAN interface)
Verify GRO is happening.
9084 MBps tput
3.44% CPU utilization
- Without fix (GRO disabled on VXLAN interface)
Verified no GRO is happening.
9084 MBps tput
5.54% CPU utilization
