The biggest barrier at this point seems to be hardware availability. People generally don't care unless they use or are going to get that hardware. Also the big benchmark data, although interesting, is usually only interesting to vendors. You probably will have to suffer out of tree for a while until the hardware becomes more available. When the hardware is more common, then the implementation details will be sorted out. Also after the 2+ years of getting TSO to work right, maybe the developers are a little gun shy at this point. - 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
