Andy,
ip + 14? How do you get this result?
Thank you.

Hi,
The obvious issue at present is that your upload rate isnt hitting
the ceiling rate you have specified, or at least the rate estimator
doesnt think it is. This could be because you've set your upload
incorrectly (what is your sync speed) or could be because you are not
accounting for the overheads and ATM characteristics in your
connection (makes the rate estimator inaccurate).
You should try adding stab overhead 40 linklayer atm to your root
qdisc.
The overhead 40 bit will be whatever number
https://github.com/moeller0/ATM_overhead_detector figures out for
you.
Just in case that just reveals the fixed overhead on IP, on eth tc sees
ip + 14 already, so you can subtract 14, which for ipoa or pppoa vcmux
means you should use a negative overhead.
