Just wanted to give you a bit more info about the raw firmware so you
can understand what was going on...

The other (raw) firmware, expects 802.11 frames from the driver.
In that case, the association state machine in the firmware is disabled, 
and any 802.3 frame received from the driver is dropped (this was the cause of 
the Tx timeouts that you saw).

The raw firmware is only useful for generating test traffic or for other 
networking applications that require 802.11 frames (e.g. roofnet).  In that 
case, you must use libpcap to inject the traffic, and set the linkmode 
parameter on the driver to 2.

Cheers,
