No, that should be ETH_ALEN+2 really, I guess - it's not taking into account the size of the address member itself at all. 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
