Hi All,
Is it possible to rate-limit aggregate bandwidth of certain ingress
packet types received on multiple interfaces using TC?
For example rate-limit all ingress PTP packet traffic received by
multiple interfaces to 100Mbps.
The tc policing action is tied to a particular interface + qdisk handle.
Thanks,
Naveen

My understanding is that TC applies to a single interface.
However, I believe there is (was) a virtual interface that could be used
to aggregate / funnel multiple interfaces into one where the TC rules
could be applied.
Sorry, I don't remember any more details about the virtual interface
other than it does (did) exist.

You would apply your TC rules to the virtual aggregate interface and
make sure they are crafted to target the specific packets as you desire.
