Date: Sat, 14 Jun 2014 23:24:20 -0700 (PDT) From: Tom Herbert <therbert@...gle.com> To: davem@...emloft.net, netdev@...r.kernel.org Subject: [PATCH v2 3/5] udp: call __skb_checksum_complete when doing full checksum In __udp_lib_checksum_complete check if checksum is being done over all the data (len is equal to skb->len) and if it is call __skb_checksum_complete instead of __skb_checksum_complete_head. This allows checksum to be saved in checksum complete.
