It is not necessarily the most efficient way to generate bulk traffic,
but I think it is a valid test.
I use non-blocking IO and poll(). It is true that both sides may have
full TX and/or RX buffers, but the code still works fine. I can adjust
my tool to request any speed any either direction, so I will see if
the bi-directionality makes a difference...
Thanks,

You probably are seeing the device layer equivalent of livelock.
Perhaps you are even sending yourself a pause frame.
Why would I? For what it's worth, I can use pktgen to send
to my self in both directions at about 990Mbps, so the hardware
can definately handle the measly 200Mbps of TCP traffic I was sending.
