Hi, I'm investigating a potential software driver bug in which a driver calls skb_tx_timestamp earlier than necessary, and I want to gather some informational data to indicate whether or not moving the function to a later point in the driver tx/rx path would actually improve the accuracy/precision.
I recall seeing some fancy graphs of this data posted to the list, and was curious if anyone had an easy way to generate a graph to indicate whether the change was an improvement or not. Specifically, the software timestamping varies enough that it is difficult to determine just at a glance whether behavior has been improved or not. I'm not 100% sure what analytical data I should be looking for. Thanks, Jake
