[Cake] overhead and mpu

[Dennis Fedtke]

Hi everyone!

thanks for your answers again.

So what about from should i expect from using the docsis keyword?
(This layer cake script + nat docsis set in advanced config)

tc -s qdisc show dev eth1.100:

Why is there no overhead showing for egress?
Why is there overhead18 + via-ethernet showing for ingress?

Thanks again =)
