Ok, I've heard what you have to say. Of the fixes you've proposed already, I prefer the device MTU one because it doesn't penalize the ip_fragment.c optimizations just because a netfilter module is loaded. Which of your already proposed patches do you prefer, and why? I'm happy to apply one or the other as an interim step to make forward progress. However, I really want to seriously consider our long term handling of fragments in netfilter meanwhile. Thanks.
