Remote checksum offload is intended to be used to get checksum offload
of encapsulated packets to work with legacy NICs (those that don't
understand encapsulation protocols). I will be posting an
implementation to Linux shortly for GUE and/or Geneve.

Thanks,
Tom

Title:          Remote checksum offload for encapsulation
Document date:  2014-08-27
Group:          Individual Submission
Pages:          9

Abstract:
   This specification 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.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
