- * Interface definitions for transmit rate control modules for the
- * Atheros driver.
- *
- * A rate control module is responsible for choosing the transmit rate
- * for each data frame. Management+control frames are always sent at
- * a fixed rate.
- *
- * Only one module may be present at a time; the driver references
- * rate control interfaces by symbol name. If multiple modules are
- * to be supported we'll need to switch to a registration-based scheme
- * as is currently done, for example, for authentication modules.
- *
- * An instance of the rate control module is attached to each device
- * at attach time and detached when the device is destroyed. The module
- * may associate data with each device and each node (station). Both
- * sets of storage are opaque except for the size of the per-node storage
- * which must be provided when the module is attached.
- *
- * The rate control module is notified for each state transition and
- * station association/reassociation. Otherwise it is queried for a
- * rate for each outgoing frame and provided status from each transmitted
- * frame. Any ancillary processing is the responsibility of the module
- * (e.g. if periodic processing is required then the module should setup
- * it's own timer).
- *
- * In addition to the transmit rate for each frame the module must also
- * indicate the number of attempts to make at the specified rate. If this
- * number is != ATH_TXMAXTRY then an additional callback is made to setup
- * additional transmit state. The rate control code is assumed to write
- * this additional data directly to the transmit descriptor.
