Hi Larry

Thanks for trying. I used iperf for my throughput testing. It has two
biderectional flavours: simultaneous (-d) and individual (-r):
-d: 39 Mbps
-r: 65 Mbps

There are some more bcma related patches to be sent out, but I don't
expect that it will change your benchmark results (as mine were similar
if not identical at each commit).
