I don't see anything wrong here, perhaps tired eyes.
If you run PPPoE and the DSL line then is ATM AAL5 with LLC/SNAP
encapsulation
altq isn't going to be very effective in cases where you have lots of ACKs
going up stream.
When altq sees an ACK it calculates 40 bytes, but that ACK is 106 bytes (2
ATM cells) on your DSL line.
I modified the token bucket regulator in the kernel to adjust to what
actually happens on the DSL line
and after that the shaper worked as expected.
I was planning to implement it properly so one could configure it from
pf.conf with some
option like "tbradapt PPPoE-ATM-AAL5-LLCSNAP" per queue so I could support
other type of links
also, but I can never find the time to actually do it.
Time to try to get the kids to sleep.
