Subject: [PATCH v3 net-next 0/8] Local Checksum Offload
Date: Fri, 8 Jan 2016 19:44:23 +0000 [thread overview]
Message-ID: <56901197.8040808@solarflare.com> (raw)
Tested with a VXLAN tunnel over a device that doesn't support inner checksum
offload (so the checksum will have been done in sw by validate_xmit_skb()).
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.

net: local checksum offload for encapsulation
net: udp: always set up for CHECKSUM_PARTIAL offload
net: enable LCO for udp_tunnel_handle_offloads() users
net: vxlan: enable local checksum offload
fou: enable LCO in FOU and GUE
net: gre: Implement LCO for GRE over IPv4
net: ip_tunnel: remove 'csum_help' argument to
iptunnel_handle_offloads
