That sounds like the driver is trying to send the packet, but card
firmware drops it. Which operation mode (Managed/Master/Monitor/Adhoc)
are you using? What kind of packet are you trying to send?

Do you mean that the source address in Ethernet header is broadcast
address? If you are using Managed mode, please note that you cannot use
anything else but your own hwaddr as the source address. In Master mode,
you should be able to send such frames out.
