I think this would break the tc actions. Some actions call pskb_expand_head() on input, which BUGs on skb_shared(skb). They can't clone the skb instead because the functions doing that don't own it, the caller would continue with the old skb. - 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
