It would increase the code size slightly. The code to bump the counters should also be extremely simple (surely we don't drop packets in more than just a few places). So, in this case, the increase in complexity seems pretty minimal. > 4) Patches that have only a little debugging/etc. value are probably > useful, but mainly for a specific set of people, and this would seem to be > best handled by external patches. External-only patches almost always rot, and are extremely hard to really share across organizations. Still, point taken. Thanks, Ben
