Re: [LARTC] Ingress utilization problem

[Mr SERBAN Rares <serban_rares@yahoo.com>]

Hi Alexey,

I read the paper of Werner Almesberger. I didn' t
understand if there are multiple instances of ingress
queueing discipline. Can you be more specific?

Also I want to do marking operation in ingress
interface. How do I do?

Thank you,

R.
