94 * i2400m_queue_work - schedule work on a i2400m's queue
96 * @i2400m: device descriptor
98 * @fn: function to run to execute work. It gets passed a 'struct
99 * work_struct' that is wrapped in a 'struct i2400m_work'. Once
100 * done, you have to (1) i2400m_put(i2400m_work->i2400m) and then
101 * (2) kfree(i2400m_work).

105 * @pl: pointer to a payload buffer that you want to pass to the _work
106 * function. Use this to pack (for example) a struct with extra
109 * @pl_size: size of the payload buffer.
111 * We do this quite often, so this just saves typing; allocate a
112 * wrapper for a i2400m, get a ref to it, pack arguments and launch

127 * i2400m_queue_work(i2400m, 1, my_work_function, GFP_KERNEL,
128 * &args, sizeof(args))
130 * And now the work function can unpack the arguments and call the
131 * real function (or do the job itself):
134 * void my_work_fn((struct work_struct *ws)
136 * struct i2400m_work *iw =
137 * container_of(ws, struct i2400m_work, ws);

206 * The WiMAX stack will call this function when a message was received
209 * For the i2400m, this is an L3L4 message, as specified in

211 * i2400m_l3l4_hdr'. Driver (and device) expect the messages to be
212 * coded in Little Endian.
214 * This function just verifies that the header declaration and the
215 * payload are consistent and then deals with it, either forwarding it
216 * to the device or procesing it locally.
218 * In the i2400m, messages are basically commands that will carry an
219 * ack, so we use i2400m_msg_to_dev() and then deliver the ack back to
220 * user space. The rx.c code might intercept the response and use it
221 * to update the driver's state, but then it will pass it on so it can
222 * be relayed back to user space.
224 * Note that asynchronous events from the device are processed and
225 * sent to user space in rx.c.
