Hi,

I tested the patch and it works well.

Thanks !

I think if we increase the constant to 1ms, we will reduce the jitter if we have
a rate between 1kpps and 10 kpps, but I guess is not a big deal.

I've plot this new graph with this patch:

Unfortunately, the sender cpu might be preempted by timer irq or other
expensive irq, so the Min/Max values are not very different I guess.

I dont understand your Min values.

At 100 pps, how is it possible to have a Min value of ~5000 ns ?
