Recent new hardware has the ability to switch between tablet mode and clamshell mode. To optimize WiFi performance, we want to be able to use different power table between modes. This patch adds a new netlink message type and cfg80211_ops function to allow userspace to trigger a power mode switch for a given wireless interface.
I'm not a fan of this at all. Too much magic. FWIW, we implemented something similar, currently with vendor commands, that simply allows to set the TX power in a more controlled fashion, i.e. allows setting TX power per band/channel range. For our device it's only 2.4 GHz vs. 5.2 GHz, but I can imagine that you might want to split it a bit further, so perhaps we need to advertise those ranges somehow. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
