I wondered about that myself. Upon investigation, my test with bcma/brcmsmac 
never worked. Without the patches, my netperf numbers for brcmsmac are RX 40.0 
and TX 59.7 Mbps.In all cases, the reported number is the maximum of 10 tries of 
3 sec each.

With the patches, my dmesg contains the following:

[  908.282281] bcma: Bus registered
[  908.353242] brcmsmac bcma0:0: mfg 4bf core 812 rev 23 class 0 irq 22

[  908.380379] brcmsmac: brcms_bcma_probe: brcms_attach failed!
[  908.381715] brcms_module_init: register returned 0

As b43 is also loaded, which may be a second problem, it is run instead of brcmsmac.
