Didn't review yet, reacting this this paragraph: To avoid regressions, it seems reasonable to make the device use a single queue by default for now. Add a way to switch multiqueue on/off using ethtool. This way guest admin can tune the device for the workload manually until we manage to imlement some self-tuning heuristics. -- MST _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
