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.
