> We found it in performance work of our EN (10G) driver By the way, it would certainly make sense for the ethernet driver to use a number of queues that matches num_online_cpus() at the time the interface is brought up. Since we can't change the # of MSI-X vectors very easily I think we need to allow for the possible CPUs, but bouncing a net interface seems lighter weight to me.
Although perhaps reloading a driver on CPU hotplug is OK too? - R. -- Roland Dreier <[email protected]> || For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/index.html _______________________________________________ ewg mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
