I'm not sure when support for Wi-Fi Direct landed, but you will need to use a kernel that's newer than that. I'm also not sure whether wl1271 supports those features at the moment. In terms of versions, you'll have to figure that out yourself. You will need to find which version of WPA Supplicant, IW and compat-wireless supports the features you want. You will then need to determine which version of the firmware that the wl1271 driver in that compat-wireless release needs and use that. > Let us know how to enable Power Management in the WL1271 driver and also kernel patches to enable the Power Management as this very critical If your kernel doesn't have the necessary support for runtime power management, then you're on your own and will have to back-port it yourself. Compat-wireless tries to produce the best functionality for older kernels, but sometimes it's simply not practical to back-port large chunks of infrastructure to older kernels. That said, if you do manage to back-port it, patches for compat or compat-wireless would be most welcome.
