Title : Remote checksum offload for encapsulation

Abstract:
This document describes remote checksum offload for encapsulation,
which is a mechanism that provides checksum offload of 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 for
an inner 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.
