I am moving this back to the list so everyone can benefit. I set both the sending and receiving AR9170 to monitor mode using airmon-ng start wlan3 I set the sending device to channel 40 5200Mhz iw wlan3 set channel 40 I run airomon-ng --channel 40 mon0 on the receiver. and I am able to send and receive a packet using a RadioTap raw sockets test program I found on the web I separately instrumented carl9170.ko so that I could observe bot the calls and the register IO's to initialize the AR9170 and set the frequency. After that worked, I sent a custom command to the AR9170 Firmware that called a routine similar to void wlan_wol_connection_monitor(void) and void wlan_send_buffered_ba(void), in this routing I set the ieee80211_hdr addresses 1-3 to all 0xff's as my experience with ethernet sugested that should always work if you do not need a reply back. i also implimented a callback function for wlan_tx_fw() in the hope that it would report any errors. Anyway I got no errors, but did not receive a packet. So i added debugging code to dump the various things in wlan_tx(), so that I could trap both the packets that were being sent and those that were not to see what was different. When I set addr2 & addr3 to 0x00, 0x12, 0x34, 0x56, 0x78, 0x9a wlan_tx_fw() started actually transmitting packets. My observations regarding carlu where just in passing. I am not using carlu, though I might have had I started with it. Being able to bypass the entire linux network stack and talk to the firmware directly, would be very useful for the projects i seem to get. I have essentially implemented a variation on carlu, using debugfs inside the carl9170 driver.
