Mhh ..

I hacked up a patch yesterday. I want to do a bit more testing before posting it, but its hard to really test the effectiveness because even without this patch my DSL line already delivers higher throughput and much better delay than it should (its a throttled SDSL line sold as ADSL). I'll try to do some testing on an ethernet link now. - 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
