Date: Fri, 2 May 2014 16:27:44 -0700 (PDT) From: Tom Herbert <therbert@...gle.com> To: davem@...emloft.net, netdev@...r.kernel.org Subject: [PATCH 0/8 v4] net: Checksum offload changes I am working on overhauling RX checksum offload. Goals of this effort are: - Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY - Preserve CHECKSUM_COMPLETE through encapsulation layers - Don't do skb_checksum more than once per packet - Unify GRO and non-GRO csum verification as much as possible - Unify the checksum functions (checksum_init) - Simply code What is in this first patch set: - Create a common "checksum_init" function which is called from TCPv{4,6} and UDPv{4,6} - Add some for RFC6936, UDP/IPv6 zero checksums - Add architecture support for csum_add and provide implementations for x86_64 and Sparc 32 and 64 bit (please test the latter) Please review carefully and test if possible, mucking with basic checksum functions is always a little precarious :-) -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
