Its time betwen two dequeues and packet transmits used by qdisc for calculation. Any of current IMQ implementations do not use it, so the calculation by qdisc may not be correct, whish causing filling physical device fifos without control. In devices with variable speed (WiFi, Modems) it causes overload because the physisal trafics is out of control. It happen only on busy boxes, like my routers where is about 70 ppl at once. In a simply test enviroment this issue will never happen. >and it would be good if you posted source code directly (not inside of diff >file) >for review purposes > > > The whole patch contain only few new files, all other are patches of the original kernel files. BTW Midnight Comander 4.6.0 contain very nice diff virtual filesystem, so you can browse .diff files like a tar archive. >also you can look at my imq version, because it is much easer to develop >since is independent from kernel. >and does not need to patch it. >http://pupa.da.ru/imq/ > > > I have play with with your version :) Having independet implementation is nice idea. I play with that idea too but it was more dificult to have stable solution in short time i need and with EOS support its quite imposible ...
