*
* @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).

*
*
* Don't #include this file directly, read on!
*
*
* 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.
