Not because I think it obviates your work, but rather because I'm curious, could you test a TSO-in-hardware driver converted to batching and see how TSO alone compares to batching for a pure TCP workload? I personally don't think it will help for that case at all as TSO likely does better job of coalescing the work _and_ reducing bus traffic as well as work in the TCP stack. - 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
