The TSO problem in the atl1 driver was never resolved, and TSO was turned off by default with commit 82c26a9d117f0178b8c1b33429014b6d99c470f6 in the 2.6.27 cycle. It was also added to the -stable tree at 2.6.26.4. http://lkml.org/lkml/2008/9/3/251 Jay -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
