	I've seen engineers even forget to account for differing behaviors
of vendors, eg: Juniper doesn't display the layer-2 header counters

	This means a 920Mb/s link may actually be 100% once you add back in
ethernet framing.  Remind folks that they are seeing the TCP/UDP throughput
and there is ethernet + IP headers involved.
