Thanks! But just one last thing. Before reading about fecn-adapt I thought
it was there so that in a bidirectional flow.
the remote end would add a FECN to frames it was sending back to the Source.
Does this mean by using fecn-adapt, only test frames are sent with fecn or
can the fecn be attached to normal data frames.
