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.

Name: draft-herbert-remotecsumoffload Revision: 00 Title: Remote checksum offload for encapsulation Document date: 2014-08-27 Group: Individual Submission Pages: 9 URL: http://www.ietf.org/internet-drafts/draft-herbert-remotecsumoffload-00.txt Status: https://datatracker.ietf.org/doc/draft-herbert-remotecsumoffload/ Htmlized: http://tools.ietf.org/html/draft-herbert-remotecsumoffload-00 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.
