Title : Remote checksum offload for encapsulation

Abstract:
This specification describes remote checksum offload, which is a
mechanism that provides checksum offload of transport checksums in
encapsulated packets using rudimentary offload capabilities found in
most Network Interface Card (NIC) devices. The outer header checksum
(e.g. that in UDP or GRE) is enabled in packets and, with some
additional meta information, a receiver is able to deduce the
checksum to be set in an encapsulated packet. Effectively this
offloads the computation of the inner checksum. Enabling the outer
checksum in encapsulation has the additional advantage that it covers
more of the packet than the inner checksum including the
encapsulation headers.
