Note that we could use the callback pointer for the XFRM case too, and I kind of thought you would understand that logical progression and implement that too :-/ That way we don't need any funny return values, there is just one and it simply triggers the callback. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
