We need another solution to this problem, because cloning an extra SKB is just rediculious overhead so isn't something we can seriously consider to solve this problem. Another option is to say this anomaly doesn't matter enough to justify the complexity we're looking at here just to fix this glitch. Other implementation possibility suggestions welcome :-) - 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
