Hi all, As Eric mentioned, this is a per-link counter. I am not sure an aggregate stat would be as useful.
As suggested by Florian, I'm planning to add a doc. As far as I can tell, I think it goes beyond just documenting this new counter: I believe sysfs-class-net needs to be added as a whole. Stephen: I have a patch for iproute2, I was planning to send it after we're done with this one, unless you want it now. Also, should I document this IFLA thing, where would be best?
