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.
