That list doesn't look too promising. I'd rather look in net/ipv4 which does have TSO/GSO related changes. I tried to bisect that but the system hangs on boot when net devices are enabled. So it may prove difficult to pin down. I may try again during the weekend. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
