Serious protocol inconistency, noticed by Aki M. Laukanen Fragment queues must expire not later than MSL after arrival the first packet.

He proposed to relax Karn algo, to be honest. Now defragmenter generates good fragmented skbs. Patch from Dave, checked, IPv6 is loaded as module. One more SMP bug in error queue processing. Well, byproducts effects of doing nw things are not less interesting sometimes.
