So you are running a tcpdump on sender, using the timestamping service from
the hardware, and the same on receiver, and then you send traffic?
How much traffic? Is it being buffered?
How do you correlate traffic?
How are the *hardware* clocks being synchronzied?
AFAIK, no NICs timestamp traffic on outgoing, tcpdump captures before the
hardware queue. A big hardware send buffer would result in significant skew.
