Addition of Gen2 switches just pushed forward the standard implementation. The RIO standard methods may be used on 1.3 switches (tested on tsi57x) as well as the standard routing table operations that have been added in our patches for 2.6.35. > > Micha Alex. -- 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/
