2009-01-07wimax: basic API: kernel/user messaging, rfkill and resetInaky Perez-Gonzalez
Implements the three basic operations provided by the stack's control interface to WiMAX devices: - Messaging channel between user space and driver/device This implements a direct communication channel between user space and the driver/device, by which free form messages can be sent back and forth. This is intended for device-specific features, vendor quirks, etc. - RF-kill framework integration Provide most of the RF-Kill integration for WiMAX drivers so that all device drivers have to do is after wimax_dev_add() is call wimax_report_rfkill_{hw,sw}() to update initial state and then every time it changes. Provides wimax_rfkill() for the kernel to call to set software RF-Kill status and/or query current hardware and software switch status. Exports wimax_rfkill() over generic netlink to user space. - Reset a WiMAX device Provides wimax_reset() for the kernel to reset a wimax device as needed and exports it over generic netlink to user space. This API is clearly limited, as it still provides no way to do the basic scan, connect and disconnect in a hardware independent way. The WiMAX case is more complex than WiFi due to the way networks are discovered and provisioned. The next developments are to add the basic operations so they can be offerent by different drivers. However, we'd like to get more vendors to jump in and provide feedback of how the user/kernel API/abstraction layer should be. The user space code for the i2400m, as of now, uses the messaging channel, but that will change as the API evolves.
