I was getting it on wi0 for a long time (bridged connection between xl0, rl0 and wi0) but just ignored it. Eventually after about 20 of those messages over an extended period of time (week or so), the wireless network slows down to treacle. I haven't noticed anything on the 100Mbit network yet but I assume it's going to do the same thing. No matter what the MTU is, there is always this 20 byte discrepency. I've checked the bug list summary and it's on there but I can't find a reasonable explanation on what it is and why it happens, if it's a configuration thing I can fix, I want to fix it even if it means disabling features. -- Matt Sealey Genesi, Manager, Developer Relations
