So I see three options: 1) Use 00:... and be happy. No problem with udev, we use an address that is actually valid. 2) Use 01:00... and fix udev so it ignores it. 3) Use 44:44..., because it is what orinoco used and fix udev so it ignores it. I would go for solution 2, 00:00:00:00:00:00 is a valid address for a device and multicast addresses are not, and that should be reflected on udev's policy. About persistent names, can we get a persistent name after the device gets its MAC address? Before that, the device is not being used and it does not matter much. -- Luis Carlos Cobo Rus GnuPG ID: 44019B60 cozybit Inc. -- 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
