[PATCH 2.6.18 0/2] LARTC: trace control for netem

[Rainer Baumann]

Hi Stephen

As discussed yesterday, here our patches to integrate trace control into netem



Trace Control for Netem: Emulate network properties such as long range dependency and self-similarity of cross-traffic.

A new option (trace) has been added to the netem command. If the trace option is used, the values for packet delay etc. are read from a pregenerated trace file, afterwards the packets are processed by the normal netem functions. The packet action values are readout from the trace file in user space and sent to kernel space via configfs.

Hi Stephen

I just wanted to ask you, if you already had time to test our trace
extension for netem as discussed on the 13th of December.

Cheers
Rainer

I looked at it some more, and want to go in and clean the configuration and buffer interface
slightly before inclusion. Once it is in I get stuck with the ABI so don't want to do something
wrong.

Just let me know, if we can help.
