My netperf results (3 sec samples) are:

TCP_MAERTS Test:  13.60 14.41 16.05 15.01 14.70 15.36 14.72 15.07 12.37 11.01
Results: max 16.05, min 11.01. Mean 14.23(1.44)

TCP_STREAM Test:   3.00  1.89  1.23  2.12  0.91  1.59  1.46  0.71  1.99  2.12
Results: max  3.00, min  0.71. Mean  1.70(0.64)

As you can see, RX is OK, but TX is quite low.

I will run the same test with brcmsmac later. Their damned Kconfig won't let me 
build both b43 and brcmsmac at the same time.
