The only possibility I know is Marvell development board like: http://avnetexpress.avnet.com/store/em/EMController/Development-Kits/Marvel= l/RD-88W-SD-8787-A0/_/R-10001817/A-10001817/An-0?action=3Dpart&catalogId=3D= 500201&langId=3D-1&storeId=3D500201 > I am running 3.11 kernel and I already build the Marvell option inside=20 > the kernel. >=20 > Is there any dongles available in the market which supports full AMP.=20 At least I couldn't find one.

Thanks for the reply. I will try to find out about the hardware while conta= cting Marvell. :) I bought a USB Bluetooth 3.0 HS + wlan combo dongle. The wlan driver is bas= ed 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 support= s new kernel (3.11 and above). =20 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 othe= r possibilities drivers or else patches available. Any suggestion or hint c= ould be really appreciated.=20 Thanks in advance, =20 Regards, Raviteja
