I'll double check that. I'm pretty sure it's an issue specific to single-stream chipsets, where all MRC functionality was left out (and thus the register access leads nowhere). I don't think this needs to consider multi-stream chipsets with only one enabled chain. - 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
