Forget what I said about the loss of transmit rate. Once I did a 
proper test, it is the same with or without the patch. For the 
BCM4318, the b43 rate is slightly reduced from using bcm43xx. The 
difference is not really great, but a reproducible reduction from 16.6 
to 14.2 Mbs with the iwconfig rate set at 54 Mbs. By comparison, the 
BCM4312 is over 20 Mbs.
