Should we give some guidance to drivers which "ignore" time stamping requests if they used up all the "slots"? Even if just temporary until they are fixed? Maybe we can add after all the fields something like: For drivers which ignore further timestamping requests when there are too many in flight, the ignored requests are currently not counted by any of the statistics. Adjust as needed, I basing this on the vague memory that this was the conclusion in the last discussion :) > * @err: Number of arbitrary timestamp generation error events that the > * hardware encountered. > */ Just to be crystal clear let's also call out that @lost is not included in @err.
