I think better walking down the packet than flow_dissect currently
does, and doing more stuff would be a computational and functional
win.
(boy do we need to start profiling!!)
While we are doing that, perhaps... well... see my next message.

ISTR that tunnels are supposed to copy the TOS byte on entry and the ECN field on exit, though there are almost certainly tunnel implementations which don’t do that.
