Also, the virtual hardware support Jouni is working on might use quiet elements, and these would have to be detected by the stations.

Agreed, anything that is more complex than this basic stuff which requires proper beacon change watching by the firmware is too much for the first cut here -- we're having enough trouble as-is, for example with the BSS struct stuff. 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
