Ethernet, hubs, switches, routers, internet backbones etc will all cause packet re-ordering. You should also expect the percentage of re-ordered frames on the net to rise and rise. But to be honest, NAPI was meant to dramatically reduce the "SMP specific" causes of packet reordering. When a driver does use NAPI, the reordering due to SMP goes way down. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
