Hi Julien,

Thanks so much for the pointers.

I back ported the patch at
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=
=3D89f927af7f3389e20c8ad24abfb3d1369f3ffc10
to the 3.12 kernel.

Now able to set the tx99 mode and configure the moni0 interface.

But I am not seeing any activity through the interface

moni0     Link encap:UNSPEC  HWaddr
00-0E-8E-45-02-DD-10-0B-00-00-00-00-00-00-00-00
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Is there any test firmware to be placed at /lib/firmware/ ?

Thanks
Senthil
