Connected directly to the N210 without any switches or other detritus in the
middle?

Even the cheezy RealTek $25.00 1GiGe PCI or PCIe cards should work for you,
particularly at lower sample rates.

I have now tested the same graph
(http://s14.postimage.org/r5ekme5pd/dump_test.jpg) at a lower speed of 1 MS/s
with the 82579LM. It still produces over-runs.
Then I have tested it with two other Intel Network cards (82583V, 82574L)
also at 1 MS/s. They don't produce overruns. But if I double the sample
rate to 2MS/s I get overruns again.
So the 82579LM definitely performs worse. But the other cards are not really
much better.
I would like to ask if anybody could try to capture data (see flowgraph) with
the USRP N210 at such speeds > 2MS/s upto 10MS/s for a longer period of time
and look if there are overflows?
