VxLAN is one of the most widely used tunneled protocols. Providing GRO support for VxLAN-encapsulated packets can benefit many per-packet based applications, like OVS.
This patchset is to support VxLAN GRO. The first patch cleans up current TCP/IPv4 GRO codes for the sake of supporting tunneled GRO. The second patch supports GRO on the VxLAN packets which have an outer IPv4 header and inner TCP/IPv4 headers.
