Subject: Re: igc: missing HW timestamps at TX

(Ctrl+Enter'd by mistake)

My question here: is there anything I can quickly try to avoid that behavior? Even when I send only a few (like 10) packets but on fast rate (5us between packets) I get missing TX HW timestamps. The receive side looks much more roboust, I cannot noticed missing HW timestamps there.

Thanks,
Ferenc
