Subject: [PATCH v4 2/3] mac80211: store tx power value from user to station

From: Ashok Raj Nagarajan <[email protected]>

This patch introduce a new driver callback drv_sta_set_txpwr. This API will
copy the transmit power value passed from user space and call the driver
callback to set the tx power for the station.

4150c57212 Johannes Berg 2007-09-17 3204 * is enabled. This should turn on the hardware and must turn on
4150c57212 Johannes Berg 2007-09-17 3205 * frame reception (for possibly enabled monitor interfaces.)
4150c57212 Johannes Berg 2007-09-17 3206 * Returns negative error codes, these may be seen in userspace,
4150c57212 Johannes Berg 2007-09-17 3207 * or zero.
4150c57212 Johannes Berg 2007-09-17 3208 * When the device is started it should not have a MAC address
4150c57212 Johannes Berg 2007-09-17 3209 * to avoid acknowledging frames before a non-monitor device
4150c57212 Johannes Berg 2007-09-17 3210 * is added.
e1781ed33a Kalle Valo 2009-12-23 3211 * Must be implemented and can sleep.
75a5f0ccfd Johannes Berg 2007-09-18 3212 *
75a5f0ccfd Johannes Berg 2007-09-18 3213 * @stop: Called after last netdevice attached to the hardware
4150c57212 Johannes Berg 2007-09-17 3214 * is disabled. This should turn off the hardware (at least
4150c57212 Johannes Berg 2007-09-17 3215 * it must turn off frame reception.)
4150c57212 Johannes Berg 2007-09-17 3216 * May be called right after add_interface if that rejects
42935ecaf4 Luis R. Rodriguez 2009-07-29 3217 * an interface. If you added any work onto the mac80211 workqueue
42935ecaf4 Luis R. Rodriguez 2009-07-29 3218 * you should ensure to cancel it on this callback.
e1781ed33a Kalle Valo 2009-12-23 3219 * Must be implemented and can sleep.
75a5f0ccfd Johannes Berg 2007-09-18 3220 *
eecc48000a Johannes Berg 2011-05-04 3221 * @suspend: Suspend the device; mac80211 itself will quiesce before and
eecc48000a Johannes Berg 2011-05-04 3222 * stop transmitting and doing any other configuration, and then
eecc48000a Johannes Berg 2011-05-04 3223 * ask the device to suspend. This is only invoked when WoWLAN is
eecc48000a Johannes Berg 2011-05-04 3224 * configured, otherwise the device is deconfigured completely and
eecc48000a Johannes Berg 2011-05-04 3225 * reconfigured at resume time.
2b4562dfd6 Johannes Berg 2011-07-02 3226 * The driver may also impose special conditions under which it
2b4562dfd6 Johannes Berg 2011-07-02 3227 * wants to use the "normal" suspend (deconfigure), say if it only
2b4562dfd6 Johannes Berg 2011-07-02 3228 * supports WoWLAN when the device is associated. In this case, it
2b4562dfd6 Johannes Berg 2011-07-02 3229 * must return 1 from this function.
eecc48000a Johannes Berg 2011-05-04 3230 *
eecc48000a Johannes Berg 2011-05-04 3231 * @resume: If WoWLAN was configured, this indicates that mac80211 is
eecc48000a Johannes Berg 2011-05-04 3232 * now resuming its operation, after this the device must be fully
eecc48000a Johannes Berg 2011-05-04 3233 * functional again. If this returns an error, the only way out is
eecc48000a Johannes Berg 2011-05-04 3234 * to also unregister the device. If it returns 1, then mac80211
eecc48000a Johannes Berg 2011-05-04 3235 * will also go through the regular complete restart on resume.
eecc48000a Johannes Berg 2011-05-04 3236 *
d13e141481 Johannes Berg 2012-06-09 3237 * @set_wakeup: Enable or disable wakeup when WoWLAN configuration is
d13e141481 Johannes Berg 2012-06-09 3238 * modified. The reason is that device_set_wakeup_enable() is
d13e141481 Johannes Berg 2012-06-09 3239 * supposed to be called when the configuration changes, not only
d13e141481 Johannes Berg 2012-06-09 3240 * in suspend().
d13e141481 Johannes Berg 2012-06-09 3241 *
75a5f0ccfd Johannes Berg 2007-09-18 3242 * @add_interface: Called when a netdevice attached to the hardware is
e37d4dffdf Bob Copeland 2008-10-20 3243 * enabled. Because it is not called for monitor mode devices, @start
75a5f0ccfd Johannes Berg 2007-09-18 3244 * and @stop must be implemented.
4150c57212 Johannes Berg 2007-09-17 3245 * The driver should perform any initialization it needs before
4150c57212 Johannes Berg 2007-09-17 3246 * the device can be enabled. The initial configuration for the
4150c57212 Johannes Berg 2007-09-17 3247 * interface is given in the conf parameter.
75a5f0ccfd Johannes Berg 2007-09-18 3248 * The callback may refuse to add an interface by returning a
75a5f0ccfd Johannes Berg 2007-09-18 3249 * negative error code (which will be seen in userspace.)
e1781ed33a Kalle Valo 2009-12-23 3250 * Must be implemented and can sleep.
75a5f0ccfd Johannes Berg 2007-09-18 3251 *
34d4bc4d41 Johannes Berg 2010-08-27 3252 * @change_interface: Called when a netdevice changes type. This callback
34d4bc4d41 Johannes Berg 2010-08-27 3253 * is optional, but only if it is supported can interface types be
34d4bc4d41 Johannes Berg 2010-08-27 3254 * switched while the interface is UP. The callback may sleep.
34d4bc4d41 Johannes Berg 2010-08-27 3255 * Note that while an interface is being switched, it will not be
34d4bc4d41 Johannes Berg 2010-08-27 3256 * found by the interface iteration callbacks.
34d4bc4d41 Johannes Berg 2010-08-27 3257 *
75a5f0ccfd Johannes Berg 2007-09-18 3258 * @remove_interface: Notifies a driver that an interface is going down.
75a5f0ccfd Johannes Berg 2007-09-18 3259 * The @stop callback is called after this if it is the last interface
75a5f0ccfd Johannes Berg 2007-09-18 3260 * and no monitor interfaces are present.
4150c57212 Johannes Berg 2007-09-17 3261 * When all interfaces are removed, the MAC address in the hardware
4150c57212 Johannes Berg 2007-09-17 3262 * must be cleared so the device no longer acknowledges packets,
4150c57212 Johannes Berg 2007-09-17 3263 * the mac_addr member of the conf structure is, however, set to the
4150c57212 Johannes Berg 2007-09-17 3264 * MAC address of the device going away.
e1781ed33a Kalle Valo 2009-12-23 3265 * Hence, this callback must be implemented. It can sleep.
4150c57212 Johannes Berg 2007-09-17 3266 *
75a5f0ccfd Johannes Berg 2007-09-18 3267 * @config: Handler for configuration requests. IEEE 802.11 code calls this
75a5f0ccfd Johannes Berg 2007-09-18 3268 * function to change hardware configuration, e.g., channel.
6dd1bf3118 Bob Copeland 2009-01-08 3269 * This function should never fail but returns a negative error code
e1781ed33a Kalle Valo 2009-12-23 3270 * if it does. The callback can sleep.
4150c57212 Johannes Berg 2007-09-17 3271 *
471b3efdfc Johannes Berg 2007-12-28 3272 * @bss_info_changed: Handler for configuration requests related to BSS
471b3efdfc Johannes Berg 2007-12-28 3273 * parameters that may vary during BSS's lifespan, and may affect low
471b3efdfc Johannes Berg 2007-12-28 3274 * level driver (e.g. assoc/disassoc status, erp parameters).
471b3efdfc Johannes Berg 2007-12-28 3275 * This function should not be used if no BSS has been set, unless
471b3efdfc Johannes Berg 2007-12-28 3276 * for association indication. The @changed parameter indicates which
e1781ed33a Kalle Valo 2009-12-23 3277 * of the bss parameters has changed when a call is made. The callback
e1781ed33a Kalle Valo 2009-12-23 3278 * can sleep.
471b3efdfc Johannes Berg 2007-12-28 3279 *
3ac64beecd Johannes Berg 2009-08-17 3280 * @prepare_multicast: Prepare for multicast filter configuration.
3ac64beecd Johannes Berg 2009-08-17 3281 * This callback is optional, and its return value is passed
3ac64beecd Johannes Berg 2009-08-17 3282 * to configure_filter(). This callback must be atomic.
3ac64beecd Johannes Berg 2009-08-17 3283 *
75a5f0ccfd Johannes Berg 2007-09-18 3284 * @configure_filter: Configure the device's RX filter.
75a5f0ccfd Johannes Berg 2007-09-18 3285 * See the section "Frame filtering" for more information.
e1781ed33a Kalle Valo 2009-12-23 3286 * This callback must be implemented and can sleep.

1b09b5568e Andrei Otcheretianski 2015-08-15 3288 * @config_iface_filter: Configure the interface's RX filter.
1b09b5568e Andrei Otcheretianski 2015-08-15 3289 * This callback is optional and is used to configure which frames
1b09b5568e Andrei Otcheretianski 2015-08-15 3290 * should be passed to mac80211. The filter_flags is the combination
1b09b5568e Andrei Otcheretianski 2015-08-15 3291 * of FIF_* flags. The changed_flags is a bit mask that indicates
1b09b5568e Andrei Otcheretianski 2015-08-15 3292 * which flags are changed.
1b09b5568e Andrei Otcheretianski 2015-08-15 3293 * This callback can sleep.

546c80c91f Luis R. Rodriguez 2008-08-14 3295 * @set_tim: Set TIM bit. mac80211 calls this function when a TIM bit
17741cdc26 Johannes Berg 2008-09-11 3296 * must be set or cleared for a given STA. Must be atomic.
11a843b7e1 Johannes Berg 2007-08-28 3297 *
75a5f0ccfd Johannes Berg 2007-09-18 3298 * @set_key: See the section "Hardware crypto acceleration"
e1781ed33a Kalle Valo 2009-12-23 3299 * This callback is only called between add_interface and
e1781ed33a Kalle Valo 2009-12-23 3300 * remove_interface calls, i.e. while the given virtual interface
dc822b5db4 Johannes Berg 2008-12-29 3301 * is enabled.
6dd1bf3118 Bob Copeland 2009-01-08 3302 * Returns a negative error code if the key can't be added.
e1781ed33a Kalle Valo 2009-12-23 3303 * The callback can sleep.
11a843b7e1 Johannes Berg 2007-08-28 3304 *

c68f4b892c Johannes Berg 2011-07-05 3310 * @set_rekey_data: If the device supports GTK rekeying, for example while the
c68f4b892c Johannes Berg 2011-07-05 3311 * host is suspended, it can assign this callback to retrieve the data
c68f4b892c Johannes Berg 2011-07-05 3312 * necessary to do GTK rekeying, this is the KEK, KCK and replay counter.
c68f4b892c Johannes Berg 2011-07-05 3313 * After rekeying was done it should (for example during resume) notify
c68f4b892c Johannes Berg 2011-07-05 3314 * userspace of the new replay counter using ieee80211_gtk_rekey_notify().

de5fad8157 Yoni Divinsky 2012-05-30 3318 * offloading. The index can be 0-3, or -1 for unsetting it.
de5fad8157 Yoni Divinsky 2012-05-30 3319 *
75a5f0ccfd Johannes Berg 2007-09-18 3320 * @hw_scan: Ask the hardware to service the scan request, no need to start
8318d78a44 Johannes Berg 2008-01-24 3321 * the scan state machine in stack. The scan must honour the channel
9050bdd858 Kalle Valo 2009-03-22 3322 * configuration done by the regulatory agent in the wiphy's
9050bdd858 Kalle Valo 2009-03-22 3323 * registered bands. The hardware (or the driver) needs to make sure
de95a54b1a Johannes Berg 2009-04-01 3324 * that power save is disabled.
de95a54b1a Johannes Berg 2009-04-01 3325 * The @req ie/ie_len members are rewritten by mac80211 to contain the
de95a54b1a Johannes Berg 2009-04-01 3326 * entire IEs after the SSID, so that drivers need not look at these
de95a54b1a Johannes Berg 2009-04-01 3327 * at all but just send them after the SSID -- mac80211 includes the
de95a54b1a Johannes Berg 2009-04-01 3328 * (extended) supported rates and HT information (where applicable).
de95a54b1a Johannes Berg 2009-04-01 3329 * When the scan finishes, ieee80211_scan_completed() must be called;
de95a54b1a Johannes Berg 2009-04-01 3330 * note that it also must be called when the scan cannot finish due to
de95a54b1a Johannes Berg 2009-04-01 3331 * any error unless this callback returned a negative error code.
e9da68ddea Johannes Berg 2018-10-18 3332 * This callback is also allowed to return the special return value 1,
e9da68ddea Johannes Berg 2018-10-18 3333 * this indicates that hardware scan isn't desirable right now and a
e9da68ddea Johannes Berg 2018-10-18 3334 * software scan should be done instead. A driver wishing to use this
e9da68ddea Johannes Berg 2018-10-18 3335 * capability must ensure its (hardware) scan capabilities aren't
e9da68ddea Johannes Berg 2018-10-18 3336 * advertised as more capable than mac80211's software scan is.
e1781ed33a Kalle Valo 2009-12-23 3337 * The callback can sleep.

b856439b1b Eliad Peller 2011-06-13 3339 * @cancel_hw_scan: Ask the low-level tp cancel the active hw scan.
b856439b1b Eliad Peller 2011-06-13 3340 * The driver should ask the hardware to cancel the scan (if possible),
b856439b1b Eliad Peller 2011-06-13 3341 * but the scan will be completed only after the driver will call

a1845fc7c5 Johannes Berg 2012-06-27 3584 * before associated. In multi-channel scenarios, a virtual interface is
a1845fc7c5 Johannes Berg 2012-06-27 3585 * bound to a channel before it is associated, but as it isn't associated
a1845fc7c5 Johannes Berg 2012-06-27 3586 * yet it need not necessarily be given airtime, in particular since any
