On-topic: Anyone working on or testing network device drivers should be using IPv6. IPv6 will exercise code paths and network behaviour that Legacy IP rarely does, in particular using multicast to do neighbour discovery. And on wireless networks when multicast will be handled differently by the AP, that makes more difference than on wired where it's mostly the MAC filters that get neglected. I've seen a number of broken drivers because their authors were only testing with Legacy IP and not IPv6. It's not hard to set up IPv6. Larry, if you need any pointers I'd be more than happy to help. -- dwmw2 -- 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
