The only possibility I know is Marvell development board like: http://avnetexpress.avnet.com/store/em/EMController/Development-Kits/Marvell/RD-88W-SD-8787-A0/_/R-10001817/A-10001817/An-0?action=part&catalogId=500201&langId=-1&storeId=500201 > I am running 3.11 kernel and I already build the Marvell option inside > the kernel. > > Is there any dongles available in the market which supports full AMP.

Thanks for the reply. I will try to find out about the hardware while contacting Marvell. :) I bought a USB Bluetooth 3.0 HS + wlan combo dongle. The wlan driver is based on realtek8192cu in the mailing list they mentioned it is based on soft AMP. I found that the realtek they didn't upgrade new driver which supports new kernel (3.11 and above). As I understood that Marvell they developed the driver with the FullAMP so that the device can run with high speed. In the same way is there any other possibilities drivers or else patches available. Any suggestion or hint could be really appreciated.
