We've done a bit of progress on this issue. Now we have the wlanconfig utility<br>
which allows us to read/write the MAC, BPP and RF registers. Is there any<br>
documentation on what values to write to these registers for continuous<br>
transmission from the WiFi chip?<br>

You need to get an utility called "wlanconfig" from your wifi vendor<br>
(either from Marvell directly or a third party module maker) and port<br>
couple of iwpriv API's such as rdmac, wrmac, rdbbp, wrbbp to read and<br>
write the MAC, BBP and RF registers from the card. These commands<br>
take one parameter that specifies the offset location that is to be<br>
read or written.<br>

Unless you port those iwpriv commands, you can't achieve continuous<br>
transmission required for FCC certification. Netcat acts as a simple<br>
utility which reads and writes data across network connections, using<br>
TCP or UDP transport protocols. It doesn't change the chip firmware<br>
behavior in any manner. You can contact any third party or a libertas<br>
developer to do the porting for you, if you don't have the resources<br>
to do that.<br>
