  *    optimization - don't waste any instructions or memory references
  *    asking if you're online or how many CPUs there are if there is
  *    only one CPU.
- * 2) Most SMP arch's #define some of these maps to be some
- *    other map specific to that arch.  Therefore, the following
- *    must be #define macros, not inlines.  To see why, examine
- *    the assembly code produced by the following.  Note that

- *        int x_map, phys_x_map;

+ * enum wimax_st - The different states of a WiMAX device
+ * @__WIMAX_ST_NULL: The device structure has been allocated and zeroed,
+ *     but still wimax_dev_add() hasn't been called. There is no state.
+ *
+ * @WIMAX_ST_DOWN: The device has been registered with the WiMAX and
+ *     networking stacks, but it is not initialized (normally that is
+ *     done with 'ifconfig DEV up' [or equivalent], which can upload
+ *     firmware and enable communications with the device).
+ *     In this state, the device is powered down and using as less
+ *     power as possible.
+ *     This state is the default after a call to wimax_dev_add(). It
+ *     is ok to have drivers move directly to %WIMAX_ST_UNINITIALIZED
+ *     or %WIMAX_ST_RADIO_OFF in _probe() after the call to
+ *     wimax_dev_add().
+ *     It is recommended that the driver leaves this state when
+ *     calling 'ifconfig DEV up' and enters it back on 'ifconfig DEV
+ *     down'.
+ *
+ * @__WIMAX_ST_QUIESCING: The device is being torn down, so no API
+ *     operations are allowed to proceed except the ones needed to
+ *     complete the device clean up process.
+ *
+ * @WIMAX_ST_UNINITIALIZED: [optional] Communication with the device
+ *     is setup, but the device still requires some configuration
+ *     before being operational.
+ *     Some WiMAX API calls might work.
+ *
+ * @WIMAX_ST_RADIO_OFF: The device is fully up; radio is off (wether
+ *     by hardware or software switches).
+ *     It is recommended to always leave the device in this state
+ *     after initialization.
+ *
+ * @WIMAX_ST_READY: The device is fully up and radio is on.
+ *
+ * @WIMAX_ST_SCANNING: [optional] The device has been instructed to
+ *     scan. In this state, the device cannot be actively connected to
+ *     a network.
+ *
+ * @WIMAX_ST_CONNECTING: The device is connecting to a network. This
+ *     state exists because in some devices, the connect process can
+ *     include a number of negotiations between user space, kernel
+ *     space and the device. User space needs to know what the device
+ *     is doing. If the connect sequence in a device is atomic and
+ *     fast, the device can transition directly to CONNECTED
+ *
+ * @WIMAX_ST_CONNECTED: The device is connected to a network.
+ *
+ * @__WIMAX_ST_INVALID: This is an invalid state used to mark the
+ *     maximum numeric value of states.
+ *
+ * Description:
+ *
+ * Transitions from one state to another one are atomic and can only
+ * be caused in kernel space with wimax_state_change(). To read the
+ * state, use wimax_state_get().
+ *
+ * States starting with __ are internal and shall not be used or
+ * referred to by drivers or userspace. They look ugly, but that's the
+ * point -- if any use is made non-internal to the stack, it is easier
+ * to catch on review.
+ *
+ * All API operations [with well defined exceptions] will take the
+ * device mutex before starting and then check the state. If the state
+ * is %__WIMAX_ST_NULL, %WIMAX_ST_DOWN, %WIMAX_ST_UNINITIALIZED or
+ * %__WIMAX_ST_QUIESCING, it will drop the lock and quit with
+ * -%EINVAL, -%ENOMEDIUM, -%ENOTCONN or -%ESHUTDOWN.
+ *
+ * The order of the definitions is important, so we can do numerical
+ * comparisons (eg: < %WIMAX_ST_RADIO_OFF means the device is not ready
+ * to operate).
+ */
+/*
+ * The allowed state transitions are described in the table below
+ * (states in rows can go to states in columns where there is an X):
+ *
+ *                                  UNINI   RADIO READY SCAN CONNEC CONNEC

+ *
+ *
+ * EXECUTING DEBUGGING ACTIONS OR NOT
+ *
+ * The main thing this framework provides is decission power to take a
+ * debug action (like printing a message) if the current debug level
+ * allows it.
+ *
+ * The decission power is at two levels: at compile-time (what does
+ * not make it is compiled out) and at run-time. The run-time
+ * selection is done per-submodule (as they are declared by the user
+ * of the framework).
+ *
+ * A call to d_test(L) (L being the target debug level) returns true
+ * if the action should be taken because the current debug levels
+ * allow it (both compile and run time).
+ *
+ * It follows that a call to d_test() that can be determined to be
+ * always false at compile time will get the code depending on it
+ * compiled out by optimization.
+ *
+ *
+ * DEBUG LEVELS
+ *
+ * It is up to the caller to define how much a debugging level is.
+ *
+ * Convention sets 0 as "no debug" (so an action marked as debug level 0
+ * will always be taken). The increasing debug levels are used for
+ * increased verbosity.
+ *
+ *
+ * USAGE
+ *
+ * Group the code in modules and submodules inside each module [which
+ * in most cases maps to Linux modules and .c files that compose
+ * those].
+ *
+ *
+ * For each module, there is:
+ *
+ *  - a MODULENAME (single word, legal C identifier)
+ *
+ *  - a debug-levels.h header file that declares the list of
+ *    submodules and that is included by all .c files that use
+ *    the debugging tools. The file name can be anything.
+ *
+ *  - some (optional) .c code to manipulate the runtime debug levels
+ *    through debugfs.
+ *
+ * The debug-levels.h file would look like:
+ *
+ *     #ifndef __debug_levels__h__
+ *     #define __debug_levels__h__
+ *
+ *     #define D_MODULENAME modulename
+ *     #define D_MASTER 10
+ *
+ *     #include <linux/wimax/debug.h>
+ *
+ *     enum d_module {
+ *             D_SUBMODULE_DECLARE(submodule_1),
+ *             D_SUBMODULE_DECLARE(submodule_2),
+ *             ...
+ *             D_SUBMODULE_DECLARE(submodule_N)
+ *     };
+ *
+ *     #endif
+ *
+ * D_MASTER is the maximum compile-time debug level; any debug actions
+ * above this will be out. D_MODULENAME is the module name (legal C
+ * identifier), which has to be unique for each module (to avoid
+ * namespace collisions during linkage). Note those #defines need to
+ * be done before #including debug.h
+ *
+ * We declare N different submodules whose debug level can be
+ * independently controlled during runtime.
+ *
+ * In a .c file of the module (and only in one of them), define the
+ * following code:
+ *
+ *     struct d_level D_LEVEL[] = {
+ *             D_SUBMODULE_DEFINE(submodule_1),
+ *             D_SUBMODULE_DEFINE(submodule_2),
+ *             ...
+ *             D_SUBMODULE_DEFINE(submodule_N),
+ *     };
+ *     size_t D_LEVEL_SIZE = ARRAY_SIZE(D_LEVEL);
+ *
+ * Externs for d_level_MODULENAME and d_level_size_MODULENAME are used
+ * and declared in this file using the D_LEVEL and D_LEVEL_SIZE macros
+ * #defined also in this file.
+ *
+ * To manipulate from user space the levels, create a debugfs dentry
+ * and then register each submodule with:
+ *
+ *     result = d_level_register_debugfs("PREFIX_", submodule_X, parent);
+ *     if (result < 0)
+ *            goto error;
+ *
+ * Where PREFIX_ is a name of your chosing. This will create debugfs
+ * file with a single numeric value that can be use to tweak it. To
+ * remove the entires, just use debugfs_remove_recursive() on 'parent'.
+ *
+ * NOTE: remember that even if this will show attached to some
+ *     particular instance of a device, the settings are *global*.
+ *
+ *
+ * On each submodule (for example, .c files), the debug infrastructure
+ * should be included like this:
+ *
+ *     #define D_SUBMODULE submodule_x     // matches one in debug-levels.h
+ *     #include "debug-levels.h"
+ *
+ * after #including all your include files.
+ *
+ *
+ * Now you can use the d_*() macros below [d_test(), d_fnstart(),
+ * d_fnend(), d_printf(), d_dump()].
+ *
+ * If their debug level is greater than D_MASTER, they will be
+ * compiled out.
+ *
+ * If their debug level is lower or equal than D_MASTER but greater
+ * than the current debug level of their submodule, they'll be
+ * ignored.
+ *
+ * Otherwise, the action will be performed.

+ *  - Initial implementation
+ *
+ *
+ * This header defines the data structures and constants used to
+ * communicate with the device.
+ *
+ * BOOTMODE/BOOTROM/FIRMWARE UPLOAD PROTOCOL
+ *
+ * The firmware upload protocol is quite simple and only requires a
+ * handful of commands. See drivers/net/wimax/i2400m/fw.c for more
+ * details.
+ *
+ * The BCF data structure is for the firmware file header.
+ *
+ *
+ * THE DATA / CONTROL PROTOCOL
+ *
+ * This is the normal protocol spoken with the device once the
+ * firmware is uploaded. It transports data payloads and control
+ * messages back and forth.
+ *
+ * It consists 'messages' that pack one or more payloads each. The
+ * format is described in detail in drivers/net/wimax/i2400m/rx.c and
+ * tx.c.
+ *
+ *
+ * THE L3L4 PROTOCOL
+ *
+ * The term L3L4 refers to Layer 3 (the device), Layer 4 (the
+ * driver/host software).
+ *
+ * This is the control protocol used by the host to control the i2400m
+ * device (scan, connect, disconnect...). This is sent to / received
+ * as control frames. These frames consist of a header and zero or
+ * more TLVs with information. We call each control frame a "message".
+ *
+ * Each message is composed of:
+ *
+ * HEADER
+ * [TLV0 + PAYLOAD0]
+ * [TLV1 + PAYLOAD1]
+ * [...]
+ * [TLVN + PAYLOADN]
+ *
+ * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are
+ * defined by a TLV structure (Type Length Value) which is a 'header'
+ * (struct i2400m_tlv_hdr) and then the payload.
+ *
+ * All integers are represented as Little Endian.
+ *
+ * - REQUESTS AND EVENTS
+ *
+ * The requests can be clasified as follows:
+ *
+ *   COMMAND:  implies a request from the host to the device requesting
+ *             an action being performed. The device will reply with a
+ *             message (with the same type as the command), status and
+ *             no (TLV) payload. Execution of a command might cause
+ *             events (of different type) to be sent later on as
+ *             device's state changes.
+ *
+ *   GET/SET:  similar to COMMAND, but will not cause other
+ *             EVENTs. The reply, in the case of GET, will contain
+ *             TLVs with the requested information.
+ *
+ *   EVENT:    asynchronous messages sent from the device, maybe as a
+ *             consequence of previous COMMANDs but disassociated from
+ *             them.
+ *
+ * Only one request might be pending at the same time (ie: don't
+ * parallelize nor post another GET request before the previous
+ * COMMAND has been acknowledged with it's corresponding reply by the
+ * device).
+ *
+ * The different requests and their formats are described below:
+ *
+ *  I2400M_MT_*   Message types
+ *  I2400M_MS_*   Message status (for replies, events)
+ *  i2400m_tlv_*  TLVs
+ *
+ * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the
+ * operation.
