Cover letter [PATCH v5 net-next 0/8] Local Checksum Offload
Re-tested VxLAN; everything else is unchanged from v4.
Changes from v4:
* Rebased series to fix conflicts with vxlan/vxlan6 merge.
Changes from v3:
* Fixed inverted checksum values introduced in v3.
* Don't mangle zero checksums in GRE.
* Clear skb->encapsulation in iptunnel_handle_offloads when not using CHECKSUM_PARTIAL, lest drivers incorrectly interpret that as a request for inner checksum offload.
Changes from v2:
* Added support for IPv4 GRE.
* Split out 'always set up for checksum offload' into its own patch.
* Removed csum_help from iptunnel_handle_offloads.
* Rewrote LCO callers to only fold once.
* Simplified nocheck handling.
Changes from v1:
* Enabled support in more encapsulation protocols.
I think it now covers everything except GRE.
* Wrote up some documentation covering TX checksum offload, LCO and RCO.
