Bandwidth limitation: qdisc conflict with third party filters

[Joel Takvorian]

Hi,
We found an issue when users use tc-based monitoring tool such as our netobserv ebpf agent and set bandwidth limitation at the same time: there's a conflict on qdisc creation resulting in the error: create ingress qdisc: file exists.
I'm not sure exactly how this issue must be addressed, but it seems several programs could cooperate using the same qdisc. There might be changes to bring both on bandwidth limitation here, and on our side on the netobserv ebpf agent.
