In your patch, the first chunk of data (which is handed back to the nic outside of rtl8169_xmit_frags) will not have is First fragment bit set when nr_frags != 0. It makes me a bit nervous. The NPQ part of your patch actually forces the start_xmit handler to wait for all previously queued packets to be sent before telling the nic that a packet may be available. I can understand that it will fix the symptoms but it will implicitly shorten the TX queue a lot. A pesky fever apart, I should be able to come with a patch before the week end. -- Ueimor - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
