I'm trying to figure out what the proper way is to expose the ingress
rate limiting knobs of the mv88e6250 (and related) to userspace. The
simpest seems to be a set of sysfs files for each port, but I'm assuming
that's a no-go (?)
So what is the right way, and has anyone looked at hooking this up?
Thanks,
Rasmus

Hi Rasmus
You need to map TC to the switch QoS functions.

This looks like the way to do it to me.

Out of curiosity - is this policing (i.e. dropping)? Are there any
switches out there which would generate pause frames if port / priority
is above a certain threshold?
