Semantically, the values are compatible. The algorithm is similar enough that this works just fine. The patch has gone through some testing that showed a visible stability improvement. - Felix -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
