I'd recommend finding (and hard-coding) a superset of all the channels that the hardware could supported, and then dynamically setting the disabled flag on those channels that the (current) regulatory information cannot do. This is something that needs to be handled throughout the code since regulatory information can already change, but adding/removing channels is something I'd really recommend against. johannes -- 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
