I disagree with the part about IPCOMP SAs. We should always calculate the MTUs for IPCOMP based on the worst-case scenario, that is, as if the packet is not compressible. This might seem unfair to the packet that has just arrived, but sooner or later we're going to get an uncompressible packet forcing the MTU down. -- Debian GNU/Linux 3.0 is out!
