> 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 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
