Your description is a bit vague... I don't know what type of traffic 
you're dealing with, what commands you're using etc.  Enabling 
promiscuous mode essentially bypasses any hardware MAC address matching 
that your controller does and thus lets everything in.  Since that 
works,  the driver is probably fine, and I suspect that you haven't 
properly configured a valid unicast MAC address.
