Yep, proper distribution with altq disabled.

That's pretty unfortunate, though ... It means that I'm forced to deal with the Comcast's buffer management which allows for more buffer bloat and is less deterministic about what packets get dropped.

I'm assuming that this won't get fixed due to PF generally not being maintained these days -- is there any other solution for shaping with active queue management (preferably RED) on FreeBSD to use instead of altq? Dummynet obviously has problems of it's own.

In any event - thanks for your help.
