Since we are queueing it to a socket, we have to NULL out the skb->dev since thee packets lifetime is being expanded outside of that allowed window. -- 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
