Actually the PHY errors are on the RX side and so don't affect the rate 
control algorithm.  What they will do however is load the host and 
potentially overrun the rx queue.  These errors are indicative of a noisy 
operating environment and are supposed to trigger the Anti Noise Immunity 
(ANI) algorithm in the HAL.  We've suspected for a while that the ANI 
support is b0rked in some way but had no time to work on it (hence the note 
in the README file).
