Don't have a packet capture, but I also noticed that this commit caused failures; symptom for me was broken squid traffic to websites using CDNs (arstechnica, twitter) and/or DNS, probably related to mixed IPv4/v6 traffic. See my followup to last week's 3.8.13-stable announcement, which was apparently not dramatic enough to warrant attention. I later found out that this regression is related to tx offloading; enabling rx & gso offloading still works. Reverting the patch restores tx offloading as well. -h
