25 *
26 * ___swabXX
27 * Generic C versions of the swab functions.
28 *
29 * ___constant_swabXX
30 * C versions that gcc can fold into a compile-time constant when
31 * the argument is a compile-time constant.
32 *
33 * __arch__swabXX[sp]?
34 * Architecture optimized versions of all the swab functions
35 * (including the s and p versions). These can be defined in
36 * asm-arch/byteorder.h. Any which are not, are defined here.
37 * __arch__swabXXs() is defined in terms of __arch__swabXXp(), which
38 * is defined in terms of __arch__swabXX(), which is in turn defined
39 * in terms of ___swabXX(x).
40 * These must be macros. They may be unsafe for arguments with
41 * side-effects.
42 *
43 * __fswabXX
44 * Inline function versions of the __arch__ macros. These _are_ safe
45 * if the arguments have side-effects. Note there are no s and p
46 * versions of these.
47 *
48 * __swabXX[sb]
49 * There are the ones you should actually use. The __swabXX versions
50 * will be a constant given a constant argument and use the arch
51 * specific code (if any) for non-constant arguments. The s and p
52 * versions always use the arch specific code (constant folding
53 * doesn't apply). They are safe to use with arguments with
54 * side-effects.
55 *
56 * swabXX[sb]
57 * Nicknames for __swabXX[sb] to use in the kernel.

10 * Will Linux ever run on such ancient beasts? if not, this file

17 * Meaning of the names I chose (vaxlinux people feel free to correct them):
18 * swahw32 swap 16-bit half-words in a 32-bit word
19 * swahb32 swap 8-bit halves of each 16-bit half-word in a 32-bit word
20 *
21 * No 64-bit support yet. I don't know NUXI conventions for long longs.
22 * I guarantee it will be a mess when it's there, though :->
23 * It will be even worse if there are conflicting 64-bit conventions.
24 * Hopefully, no one ever used 64-bit objects on NUXI machines.

130/**
131 * enum wimax_st - The different states of a WiMAX device
132 * @__WIMAX_ST_NULL: The device structure has been allocated and zeroed,
133 * but still wimax_dev_add() hasn't been called. There is no state.
134 *
135 * @WIMAX_ST_DOWN: The device has been registered with the WiMAX and
136 * networking stacks, but it is not initialized (normally that is
137 * done with 'ifconfig DEV up' [or equivalent], which can upload
138 * firmware and enable communications with the device).
139 * In this state, the device is powered down and using as less
140 * power as possible.
141 * This state is the default after a call to wimax_dev_add(). It
142 * is ok to have drivers move directly to %WIMAX_ST_UNINITIALIZED
143 * or %WIMAX_ST_RADIO_OFF in _probe() after the call to
144 * wimax_dev_add().
145 * It is recommended that the driver leaves this state when
146 * calling 'ifconfig DEV up' and enters it back on 'ifconfig DEV
147 * down'.
148 *
149 * @__WIMAX_ST_QUIESCING: The device is being torn down, so no API
150 * operations are allowed to proceed except the ones needed to
151 * complete the device clean up process.
152 *
153 * @WIMAX_ST_UNINITIALIZED: [optional] Communication with the device
154 * is setup, but the device still requires some configuration
155 * before being operational.
156 * Some WiMAX API calls might work.
157 *
158 * @WIMAX_ST_RADIO_OFF: The device is fully up; radio is off (wether
159 * by hardware or software switches).
160 * It is recommended to always leave the device in this state
161 * after initialization.
162 *
163 * @WIMAX_ST_READY: The device is fully up and radio is on.
164 *
165 * @WIMAX_ST_SCANNING: [optional] The device has been instructed to
166 * scan. In this state, the device cannot be actively connected to
167 * a network.
168 *
169 * @WIMAX_ST_CONNECTING: The device is connecting to a network. This
170 * state exists because in some devices, the connect process can
171 * include a number of negotiations between user space, kernel
172 * space and the device. User space needs to know what the device
173 * is doing. If the connect sequence in a device is atomic and
174 * fast, the device can transition directly to CONNECTED
175 *
176 * @WIMAX_ST_CONNECTED: The device is connected to a network.
177 *
178 * @__WIMAX_ST_INVALID: This is an invalid state used to mark the
179 * maximum numeric value of states.
180 *
181 * Description:
182 *
183 * Transitions from one state to another one are atomic and can only
184 * be caused in kernel space with wimax_state_change(). To read the
185 * state, use wimax_state_get().
186 *
187 * States starting with __ are internal and shall not be used or
188 * referred to by drivers or userspace. They look ugly, but that's the
189 * point -- if any use is made non-internal to the stack, it is easier
190 * to catch on review.
191 *
192 * All API operations [with well defined exceptions] will take the
193 * device mutex before starting and then check the state. If the state
194 * is %__WIMAX_ST_NULL, %WIMAX_ST_DOWN, %WIMAX_ST_UNINITIALIZED or
195 * %__WIMAX_ST_QUIESCING, it will drop the lock and quit with
196 * -%EINVAL, -%ENOMEDIUM, -%ENOTCONN or -%ESHUTDOWN.
197 *
198 * The order of the definitions is important, so we can do numerical
199 * comparisons (eg: < %WIMAX_ST_RADIO_OFF means the device is not ready
200 * to operate).
201 */
202/*
203 * The allowed state transitions are described in the table below
204 * (states in rows can go to states in columns where there is an X):
205 *
206 * UNINI RADIO READY SCAN CONNEC CONNEC
207 * NULL DOWN QUIESCING TIALIZED OFF NING TING TED

27 * EXECUTING DEBUGGING ACTIONS OR NOT
28 *
29 * The main thing this framework provides is decission power to take a
30 * debug action (like printing a message) if the current debug level
31 * allows it.
32 *
33 * The decission power is at two levels: at compile-time (what does
34 * not make it is compiled out) and at run-time. The run-time
35 * selection is done per-submodule (as they are declared by the user
36 * of the framework).
37 *
38 * A call to d_test(L) (L being the target debug level) returns true
39 * if the action should be taken because the current debug levels
40 * allow it (both compile and run time).
41 *
42 * It follows that a call to d_test() that can be determined to be
43 * always false at compile time will get the code depending on it
44 * compiled out by optimization.
45 *
46 *
47 * DEBUG LEVELS
48 *
49 * It is up to the caller to define how much a debugging level is.
50 *
51 * Convention sets 0 as "no debug" (so an action marked as debug level 0
52 * will always be taken). The increasing debug levels are used for
53 * increased verbosity.
54 *
55 *
56 * USAGE
57 *
58 * Group the code in modules and submodules inside each module [which
59 * in most cases maps to Linux modules and .c files that compose
60 * those].
61 *
62 *
63 * For each module, there is:
64 *
65 * - a MODULENAME (single word, legal C identifier)
66 *
67 * - a debug-levels.h header file that declares the list of
68 * submodules and that is included by all .c files that use
69 * the debugging tools. The file name can be anything.
70 *
71 * - some (optional) .c code to manipulate the runtime debug levels
72 * through debugfs.
73 *
74 * The debug-levels.h file would look like:
75 *
76 * #ifndef __debug_levels__h__
77 * #define __debug_levels__h__
78 *
79 * #define D_MODULENAME modulename
80 * #define D_MASTER 10
81 *
82 * #include <linux/wimax/debug.h>
83 *
84 * enum d_module {
85 * D_SUBMODULE_DECLARE(submodule_1),
86 * D_SUBMODULE_DECLARE(submodule_2),
87 * ...
88 * D_SUBMODULE_DECLARE(submodule_N)
89 * };
90 *
91 * #endif
92 *
93 * D_MASTER is the maximum compile-time debug level; any debug actions
94 * above this will be out. D_MODULENAME is the module name (legal C
95 * identifier), which has to be unique for each module (to avoid
96 * namespace collisions during linkage). Note those #defines need to
97 * be done before #including debug.h
98 *
99 * We declare N different submodules whose debug level can be
100 * independently controlled during runtime.
101 *
102 * In a .c file of the module (and only in one of them), define the
103 * following code:
104 *
105 * struct d_level D_LEVEL[] = {
106 * D_SUBMODULE_DEFINE(submodule_1),
107 * D_SUBMODULE_DEFINE(submodule_2),
108 * ...
109 * D_SUBMODULE_DEFINE(submodule_N),
110 * };
111 * size_t D_LEVEL_SIZE = ARRAY_SIZE(D_LEVEL);
112 *
113 * Externs for d_level_MODULENAME and d_level_size_MODULENAME are used
114 * and declared in this file using the D_LEVEL and D_LEVEL_SIZE macros
115 * #defined also in this file.
116 *
117 * To manipulate from user space the levels, create a debugfs dentry
118 * and then register each submodule with:
119 *
120 * result = d_level_register_debugfs("PREFIX_", submodule_X, parent);
121 * if (result < 0)
122 * goto error;
123 *
124 * Where PREFIX_ is a name of your chosing. This will create debugfs
125 * file with a single numeric value that can be use to tweak it. To
126 * remove the entires, just use debugfs_remove_recursive() on 'parent'.
127 *
128 * NOTE: remember that even if this will show attached to some
129 * particular instance of a device, the settings are *global*.
130 *
131 *
132 * On each submodule (for example, .c files), the debug infrastructure
133 * should be included like this:
134 *
135 * #define D_SUBMODULE submodule_x // matches one in debug-levels.h
136 * #include "debug-levels.h"
137 *
138 * after #including all your include files.
139 *
140 *
141 * Now you can use the d_*() macros below [d_test(), d_fnstart(),
142 * d_fnend(), d_printf(), d_dump()].
143 *
144 * If their debug level is greater than D_MASTER, they will be
145 * compiled out.
146 *
147 * If their debug level is lower or equal than D_MASTER but greater
148 * than the current debug level of their submodule, they'll be
149 * ignored.
150 *
151 * Otherwise, the action will be performed.

37 * - Initial implementation
38 *
39 *
40 * This header defines the data structures and constants used to
41 * communicate with the device.
42 *
43 * BOOTMODE/BOOTROM/FIRMWARE UPLOAD PROTOCOL
44 *
45 * The firmware upload protocol is quite simple and only requires a
46 * handful of commands. See drivers/net/wimax/i2400m/fw.c for more
47 * details.
48 *
49 * The BCF data structure is for the firmware file header.
50 *
51 *
52 * THE DATA / CONTROL PROTOCOL
53 *
54 * This is the normal protocol spoken with the device once the
55 * firmware is uploaded. It transports data payloads and control
56 * messages back and forth.
57 *
58 * It consists 'messages' that pack one or more payloads each. The
59 * format is described in detail in drivers/net/wimax/i2400m/rx.c and
60 * tx.c.
61 *
62 *
63 * THE L3L4 PROTOCOL
64 *
65 * The term L3L4 refers to Layer 3 (the device), Layer 4 (the
66 * driver/host software).
67 *
68 * This is the control protocol used by the host to control the i2400m
69 * device (scan, connect, disconnect...). This is sent to / received
70 * as control frames. These frames consist of a header and zero or
71 * more TLVs with information. We call each control frame a "message".
72 *
73 * Each message is composed of:
74 *
75 * HEADER
76 * [TLV0 + PAYLOAD0]
77 * [TLV1 + PAYLOAD1]
78 * [...]
79 * [TLVN + PAYLOADN]
80 *
81 * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are
82 * defined by a TLV structure (Type Length Value) which is a 'header'
83 * (struct i2400m_tlv_hdr) and then the payload.
84 *
85 * All integers are represented as Little Endian.
86 *
87 * - REQUESTS AND EVENTS
88 *
89 * The requests can be clasified as follows:
90 *
91 * COMMAND: implies a request from the host to the device requesting
92 * an action being performed. The device will reply with a
93 * message (with the same type as the command), status and
94 * no (TLV) payload. Execution of a command might cause
95 * events (of different type) to be sent later on as
96 * device's state changes.
97 *
98 * GET/SET: similar to COMMAND, but will not cause other
99 * EVENTs. The reply, in the case of GET, will contain
100 * TLVs with the requested information.
101 *
102 * EVENT: asynchronous messages sent from the device, maybe as a
103 * consequence of previous COMMANDs but disassociated from
104 * them.
105 *
106 * Only one request might be pending at the same time (ie: don't
107 * parallelize nor post another GET request before the previous
108 * COMMAND has been acknowledged with it's corresponding reply by the
109 * device).
110 *
111 * The different requests and their formats are described below:
112 *
113 * I2400M_MT_* Message types
114 * I2400M_MS_* Message status (for replies, events)
115 * i2400m_tlv_* TLVs
116 *
117 * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the
118 * operation.

22 *
23 *
24 * The WiMAX stack provides an API for controlling and managing the
25 * system's WiMAX devices. This API affects the control plane; the
26 * data plane is accessed via the network stack (netdev).
27 *
28 * Parts of the WiMAX stack API and notifications are exported to
29 * user space via Generic Netlink. In user space, libwimax (part of
30 * the wimax-tools package) provides a shim layer for accessing those
31 * calls.
32 *
33 * The API is standarized for all WiMAX devices and different drivers
34 * implement the backend support for it. However, device-specific
35 * messaging pipes are provided that can be used to issue commands and
36 * receive notifications in free form.
37 *
38 * Currently the messaging pipes are the only means of control as it
39 * is not known (due to the lack of more devices in the market) what
40 * will be a good abstraction layer. Expect this to change as more
41 * devices show in the market. This API is designed to be growable in
42 * order to address this problem.
43 *
44 * USAGE
45 *
46 * Embed a `struct wimax_dev` at the beginning of the the device's
47 * private structure, initialize and register it. For details, see
48 * `struct wimax_dev`s documentation.
49 *
50 * Once this is done, wimax-tools's libwimaxll can be used to
51 * communicate with the driver from user space. You user space
52 * application does not have to forcibily use libwimaxll and can talk
53 * the generic netlink protocol directly if desired.
54 *
55 * Remember this is a very low level API that will to provide all of
56 * WiMAX features. Other daemons and services running in user space
57 * are the expected clients of it. They offer a higher level API that
58 * applications should use (an example of this is the Intel's WiMAX
59 * Network Service for the i2400m).
60 *
61 * DESIGN
62 *
63 * Although not set on final stone, this very basic interface is
64 * mostly completed. Remember this is meant to grow as new common
65 * operations are decided upon. New operations will be added to the
66 * interface, intent being on keeping backwards compatibility as much
67 * as possible.
68 *
69 * This layer implements a set of calls to control a WiMAX device,
70 * exposing a frontend to the rest of the kernel and user space (via
71 * generic netlink) and a backend implementation in the driver through
72 * function pointers.
73 *
74 * WiMAX devices have a state, and a kernel-only API allows the
75 * drivers to manipulate that state. State transitions are atomic, and
76 * only some of them are allowed (see `enum wimax_st`).
77 *
78 * Most API calls will set the state automatically; in most cases
79 * drivers have to only report state changes due to external
80 * conditions.
81 *
82 * All API operations are 'atomic', serialized thorough a mutex in the
83 * `struct wimax_dev`.
84 *
85 * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK
86 *
87 * The API is exported to user space using generic netlink (other
88 * methods can be added as needed).
89 *
90 * There is a Generic Netlink Family named "WiMAX", where interfaces
91 * supporting the WiMAX interface receive commands and broadcast their
92 * signals over a multicast group named "msg".
93 *
94 * Mapping to the source/destination interface is done by an interface
95 * index attribute.
96 *
97 * For user-to-kernel traffic (commands) we use a function call
98 * marshalling mechanism, where a message X with attributes A, B, C
99 * sent from user space to kernel space means executing the WiMAX API
100 * call wimax_X(A, B, C), sending the results back as a message.
101 *
102 * Kernel-to-user (notifications or signals) communication is sent
103 * over multicast groups. This allows to have multiple applications
104 * monitoring them.
105 *
106 * Each command/signal gets assigned it's own attribute policy. This
107 * way the validator will verify that all the attributes in there are
108 * only the ones that should be for each command/signal. Thing of an
109 * attribute mapping to a type+argumentname for each command/signal.
110 *
111 * If we had a single policy for *all* commands/signals, after running
112 * the validator we'd have to check "does this attribute belong in
113 * here"? for each one. It can be done manually, but it's just easier
114 * to have the validator do that job with multiple policies. As well,
115 * it makes it easier to later expand each command/signal signature
116 * without affecting others and keeping the namespace more or less
117 * sane. Not that it is too complicated, but it makes it even easier.
118 *
119 * No state information is maintained in the kernel for each user
120 * space connection (the connection is stateless).
121 *
122 * TESTING FOR THE INTERFACE AND VERSIONING
123 *
124 * If network interface X is a WiMAX device, there will be a Generic
125 * Netlink family named "WiMAX X" and the device will present a
126 * "wimax" directory in it's network sysfs directory
127 * (/sys/class/net/DEVICE/wimax) [used by HAL].
128 *
129 * The inexistence of any of these means the device does not support
130 * this WiMAX API.
131 *
132 * By querying the generic netlink controller, versioning information
133 * and the multicast groups available can be found. Applications using
134 * the interface can either rely on that or use the generic netlink
135 * controller to figure out which generic netlink commands/signals are
136 * supported.
137 *
138 * NOTE: this versioning is a last resort to avoid hard
139 * incompatibilities. It is the intention of the design of this
140 * stack not to introduce backward incompatible changes.
141 *
142 * The version code has to fit in one byte (restrictions imposed by
143 * generic netlink); we use `version / 10` for the major version and
144 * `version % 10` for the minor. This gives 9 minors for each major
145 * and 25 majors.
146 *
147 * The version change protocol is as follow:
148 *
149 * - Major versions: needs to be increased if an existing message/API
150 * call is changed or removed. Doesn't need to be changed if a new
151 * message is added.
152 *
153 * - Minor version: needs to be increased if new messages/API calls are
154 * being added or some other consideration that doesn't impact the
155 * user-kernel interface too much (like some kind of bug fix) and
156 * that is kind of left up in the air to common sense.
157 *
158 * User space code should not try to work if the major version it was
159 * compiled for differs from what the kernel offers. As well, if the
160 * minor version of the kernel interface is lower than the one user
161 * space is expecting (the one it was compiled for), the kernel
162 * might be missing API calls; user space shall be ready to handle
163 * said condition. Use the generic netlink controller operations to
164 * find which ones are supported and which not.
165 *
166 * libwimaxll:wimaxll_open() takes care of checking versions.
167 *
168 * THE OPERATIONS:
169 *
170 * Each operation is defined in its on file (drivers/net/wimax/op-*.c)
171 * for clarity. The parts needed for an operation are:
172 *
173 * - a function pointer in `struct wimax_dev`: optional, as the
174 * operation might be implemented by the stack and not by the
175 * driver.
176 *
177 * All function pointers are named wimax_dev->op_*(), and drivers
178 * must implement them except where noted otherwise.
179 *
180 * - When exported to user space, a `struct nla_policy` to define the
181 * attributes of the generic netlink command and a `struct genl_ops`
182 * to define the operation.
183 *
184 * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>)
185 * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in
186 * include/linux/wimax.h; this file is intended to be cloned by user
187 * space to gain access to those declarations.
188 *
189 * A few caveats to remember:
190 *
191 * - Need to define attribute numbers starting in 1; otherwise it
192 * fails.
193 *
194 * - the `struct genl_family` requires a maximum attribute id; when
195 * defining the `struct nla_policy` for each message, it has to have
196 * an array size of WIMAX_GNL_ATTR_MAX+1.
197 *
198 * THE PIPE INTERFACE:
199 *
200 * This interface is kept intentionally simple. The driver can send
201 * and receive free-form messages to/from user space through a
202 * pipe. See drivers/net/wimax/op-msg.c for details.
203 *
204 * The kernel-to-user messages are sent with
205 * wimax_msg(). user-to-kernel messages are delivered via
206 * wimax_dev->op_msg_from_user().
207 *
208 * RFKILL:
209 *
210 * RFKILL support is built into the wimax_dev layer; the driver just
211 * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in
212 * the hardware or software RF kill switches. When the stack wants to
213 * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(),
214 * which the driver implements.
215 *
216 * User space can set the software RF Kill switch by calling
217 * wimax_rfkill().
218 *
219 * The code for now only supports devices that don't require polling;
220 * If the device needs to be polled, create a self-rearming delayed
221 * work struct for polling or look into adding polled support to the
222 * WiMAX stack.
223 *
224 * When initializing the hardware (_probe), after calling
225 * wimax_dev_add(), query the device for it's RF Kill switches status
226 * and feed it back to the WiMAX stack using
227 * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always
228 * report it as ON.
229 *
230 * NOTE: the wimax stack uses an inverted terminology to that of the
231 * RFKILL subsystem:
232 *
233 * - ON: radio is ON, RFKILL is DISABLED or OFF.
234 * - OFF: radio is OFF, RFKILL is ENABLED or ON.
235 *
236 * MISCELLANEOUS OPS:
237 *
238 * wimax_reset() can be used to reset the device to power on state; by
239 * default it issues a warm reset that maintains the same device
240 * node. If that is not possible, it falls back to a cold reset
241 * (device reconnect). The driver implements the backend to this
242 * through wimax_dev->op_reset().

271 * change the RF Kill software switch (WIMAX_RF_ON or
272 * WIMAX_RF_OFF).
273 * If such hardware support is not present, it is assumed the
274 * radio cannot be switched off and it is always on (and the stack
275 * will error out when trying to switch it off). In such case,
276 * this function pointer can be left as NULL.
277 *
278 * @op_reset: [fill] Driver specific operation to reset the
279 * device.
280 * This operation should always attempt first a warm reset that
281 * does not disconnect the device from the bus and return 0.
282 * If that fails, it should resort to some sort of cold or bus
283 * reset (even if it implies a bus disconnection and device
284 * dissapearance). In that case, -ENODEV should be returned to
285 * indicate the device is gone.
286 * This operation has to be synchronous, and return only when the
287 * reset is complete. In case of having had to resort to bus/cold
288 * reset implying a device disconnection, the call is allowed to
289 * return inmediately.
290 * NOTE: wimax_dev->mutex is NOT locked when this op is being
291 * called; however, wimax_dev->mutex_reset IS locked to ensure
292 * serialization of calls to wimax_reset().
293 * See wimax_reset()'s documentation.
294 *
295 * @name: [fill] A way to identify this device. We need to register a
296 * name with many subsystems (input for RFKILL, workqueue
297 * creation, etc). We can't use the network device name as that
298 * might change and in some instances we don't know it yet (until
299 * we don't call register_netdev()). So we generate an unique one
300 * using the driver name and device bus id, place it here and use
301 * it across the board. Recommended naming:
302 * DRIVERNAME-BUSNAME:BUSID (dev->bus->name, dev->bus_id).
303 *
304 * @id_table_node: [private] link to the list of wimax devices kept by
305 * id-table.c. Protected by it's own spinlock.
306 *
307 * @mutex: [private] Serializes all concurrent access and execution of
308 * operations.
309 *
310 * @mutex_reset: [private] Serializes reset operations. Needs to be a
311 * different mutex because as part of the reset operation, the
312 * driver has to call back into the stack to do things such as
313 * state change, that require wimax_dev->mutex.
314 *
315 * @state: [private] Current state of the WiMAX device.
316 *

324 * @rf_hw: [private] State of the hardware radio switch (OFF/ON)
325 *
326 * Description:
327 * This structure defines a common interface to access all WiMAX
328 * devices from different vendors and provides a common API as well as
329 * a free-form device-specific messaging channel.
330 *
331 * Usage:
332 * 1. Embed a &struct wimax_dev at *the beginning* the network
333 * device structure so that netdev_priv() points to it.
334 *
335 * 2. memset() it to zero
336 *
337 * 3. Initialize with wimax_dev_init(). This will leave the WiMAX
338 * device in the %__WIMAX_ST_NULL state.
339 *
340 * 4. Fill all the fields marked with [fill]; once called
341 * wimax_dev_add(), those fields CANNOT be modified.
342 *
343 * 5. Call wimax_dev_add() *after* registering the network
344 * device. This will leave the WiMAX device in the %WIMAX_ST_DOWN
345 * state.
346 * Protect the driver's net_device->open() against succeeding if
347 * the wimax device state is lower than %WIMAX_ST_DOWN.
348 *
349 * 6. Select when the device is going to be turned on/initialized;
350 * for example, it could be initialized on 'ifconfig up' (when the
351 * netdev op 'open()' is called on the driver).
352 *
353 * When the device is initialized (at `ifconfig up` time, or right
354 * after calling wimax_dev_add() from _probe(), make sure the
355 * following steps are taken
356 *
357 * a. Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so
358 * some API calls that shouldn't work until the device is ready
359 * can be blocked.
360 *
361 * b. Initialize the device. Make sure to turn the SW radio switch
362 * off and move the device to state %WIMAX_ST_RADIO_OFF when
363 * done. When just initialized, a device should be left in RADIO
364 * OFF state until user space devices to turn it on.
365 *
366 * c. Query the device for the state of the hardware rfkill switch
367 * and call wimax_rfkill_report_hw() and wimax_rfkill_report_sw()
368 * as needed. See below.
369 *
370 * wimax_dev_rm() undoes before unregistering the network device. Once
371 * wimax_dev_add() is called, the driver can get called on the
372 * wimax_dev->op_* function pointers
373 *
374 * CONCURRENCY:
375 *
376 * The stack provides a mutex for each device that will disallow API
377 * calls happening concurrently; thus, op calls into the driver
378 * through the wimax_dev->op*() function pointers will always be
379 * serialized and *never* concurrent.
380 *
381 * For locking, take wimax_dev->mutex is taken; (most) operations in
382 * the API have to check for wimax_dev_is_ready() to return 0 before
383 * continuing (this is done internally).
384 *
385 * REFERENCE COUNTING:
386 *

394 * At startup, both HW and SW radio switchess are assumed to be off.
395 *
396 * At initialization time [after calling wimax_dev_add()], have the
397 * driver query the device for the status of the software and hardware
398 * RF kill switches and call wimax_report_rfkill_hw() and
399 * wimax_rfkill_report_sw() to indicate their state. If any is
400 * missing, just call it to indicate it is ON (radio always on).
401 *
402 * Whenever the driver detects a change in the state of the RF kill
403 * switches, it should call wimax_report_rfkill_hw() or
404 * wimax_report_rfkill_sw() to report it to the stack.
