27 | * DOC: Introduction | |
28 | * | |
29 | * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges | |
30 | * userspace and drivers, and offers some utility functionality associated | |
31 | * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used | |
32 | * by all modern wireless drivers in Linux, so that they offer a consistent | |
33 | * API through nl80211. For backward compatibility, cfg80211 also offers | |
34 | * wireless extensions to userspace, but hides them from drivers completely. | |
35 | * | |
36 | * Additionally, cfg80211 contains code to help enforce regulatory spectrum | |
37 | * use restrictions. | |

42 | * DOC: Device registration | |
43 | * | |
44 | * In order for a driver to use cfg80211, it must register the hardware device | |
45 | * with cfg80211. This happens through a number of hardware capability structs | |
46 | * described below. | |
47 | * | |
48 | * The fundamental structure for each device is the 'wiphy', of which each | |
49 | * instance describes a physical wireless device connected to the system. Each | |
50 | * such wiphy can have zero, one, or many virtual interfaces associated with | |
51 | * it, which need to be identified as such by pointing the network interface's | |
52 | * @ieee80211_ptr pointer to a &struct wireless_dev which further describes | |
53 | * the wireless part of the interface, normally this struct is embedded in the | |
54 | * network interface's private data area. Drivers can optionally allow creating | |
55 | * or destroying virtual interfaces on the fly, but without at least one or the | |
56 | * ability to create some the wireless device isn't useful. | |
57 | * | |
58 | * Each wiphy structure contains device capability information, and also has | |
59 | * a pointer to the various operations the driver offers. The definitions and | |
60 | * structures here describe these capabilities in detail. | |

3759 | * Authentication/(Re)Association Request frames. This call does not | |
3760 | * request an immediate disassociation or reassociation with the current | |

77765eaf VT |
3870 | * |
3871 | * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode. | |
3872 | * Parameters include ACL policy, an array of MAC address of stations | |
3873 | * and the number of MAC addresses. If there is already a list in driver | |
3874 | * this new list replaces the existing one. Driver has to clear its ACL | |
3875 | * when number of MAC addresses entries is passed as 0. Drivers which | |
3876 | * advertise the support for MAC based ACL have to implement this callback. | |
04f39047 SW |
3877 | * |
3878 | * @start_radar_detection: Start radar detection in the driver. | |
8bf24293 | 3879 | * |
26ec17a1 OM |
3880 | * @end_cac: End running CAC, probably because a related CAC |
3881 | * was finished on another phy. | |
3882 | * | |
8bf24293 JM |
3883 | * @update_ft_ies: Provide updated Fast BSS Transition information to the |
3884 | * driver. If the SME is in the driver/firmware, this information can be | |
3885 | * used in building Authentication and Reassociation Request frames. | |
5de17984 AS |
3886 | * |
3887 | * @crit_proto_start: Indicates a critical protocol needs more link reliability | |
3888 | * for a given duration (milliseconds). The protocol is provided so the | |
3889 | * driver can take the most appropriate actions. | |
3890 | * @crit_proto_stop: Indicates critical protocol no longer needs increased link | |
3891 | * reliability. This operation can not fail. | |
be29b99a | 3892 | * @set_coalesce: Set coalesce parameters. |
16ef1fe2 | 3893 | * |
97dc94f1 MK |
3894 | * @channel_switch: initiate channel-switch procedure (with CSA). Driver is |
3895 | * responsible for veryfing if the switch is possible. Since this is | |
3896 | * inherently tricky driver may decide to disconnect an interface later | |
3897 | * with cfg80211_stop_iface(). This doesn't mean driver can accept | |
3898 | * everything. It should do it's best to verify requests and reject them | |
3899 | * as soon as possible. | |
fa9ffc74 KP |
3900 | * |
3901 | * @set_qos_map: Set QoS mapping information to the driver | |
e16821bc JM |
3902 | * |
3903 | * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the | |
3904 | * given interface This is used e.g. for dynamic HT 20/40 MHz channel width | |
3905 | * changes during the lifetime of the BSS. | |
960d01ac JB |
3906 | * |
3907 | * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device | |
3908 | * with the given parameters; action frame exchange has been handled by | |
3909 | * userspace so this just has to modify the TX path to take the TS into | |
3910 | * account. | |
3911 | * If the admitted time is 0 just validate the parameters to make sure | |
3912 | * the session can be created at all; it is valid to just always return | |
3913 | * success for that but that may result in inefficient behaviour (handshake | |
3914 | * with the peer followed by immediate teardown when the addition is later | |
3915 | * rejected) | |
3916 | * @del_tx_ts: remove an existing TX TS | |
6e0bd6c3 RL |
3917 | * |
3918 | * @join_ocb: join the OCB network with the specified parameters | |
3919 | * (invoked with the wireless_dev mutex held) | |

3921 | * (invoked with the wireless_dev mutex held) | |
1057d35e AN |
3922 | * |
3923 | * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver | |
3924 | * is responsible for continually initiating channel-switching operations | |
3925 | * and returning to the base channel for communication with the AP. | |
3926 | * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both | |
3927 | * peers must be on the base channel when the call completes. | |
cb3b7d87 AB |
3928 | * @start_nan: Start the NAN interface. |
3929 | * @stop_nan: Stop the NAN interface. | |
a442b761 AB |
3930 | * @add_nan_func: Add a NAN function. Returns negative value on failure. |
3931 | * On success @nan_func ownership is transferred to the driver and | |
3932 | * it may access it outside of the scope of this function. The driver | |
3933 | * should free the @nan_func when no longer needed by calling | |
3934 | * cfg80211_free_nan_func(). | |
3935 | * On success the driver should assign an instance_id in the | |
3936 | * provided @nan_func. | |
3937 | * @del_nan_func: Delete a NAN function. | |
a5a9dcf2 AB |
3938 | * @nan_change_conf: changes NAN configuration. The changed parameters must |
3939 | * be specified in @changes (using &enum cfg80211_nan_conf_changes); | |
3940 | * All other parameters must be ignored. | |

3941 | * |
3942 | * @set_multicast_to_unicast: configure multicast to unicast conversion for BSS | |
3a00df57 | 3943 | * |
52539ca8 THJ |
3944 | * @get_txq_stats: Get TXQ stats for interface or phy. If wdev is %NULL, this |
3945 | * function should return phy stats, and interface stats otherwise. | |
3946 | * | |
3a00df57 AS |
3947 | * @set_pmk: configure the PMK to be used for offloaded 802.1X 4-Way handshake. |
3948 | * If not deleted through @del_pmk the PMK remains valid until disconnect | |
3949 | * upon which the driver should clear it. | |
3950 | * (invoked with the wireless_dev mutex held) | |
3951 | * @del_pmk: delete the previously configured PMK for the given authenticator. | |
3952 | * (invoked with the wireless_dev mutex held) | |
40cbfa90 SD |
3953 | * |
3954 | * @external_auth: indicates result of offloaded authentication processing from | |
3955 | * user space | |
2576a9ac DK |

3964 | * |
3965 | * @update_owe_info: Provide updated OWE info to driver. Driver implementing SME | |
3966 | * but offloading OWE processing to the user space will get the updated | |
3967 | * DH IE through this interface. | |
5ab92e7f RM |
3968 | * |
3969 | * @probe_mesh_link: Probe direct Mesh peer's link quality by sending data frame | |
3970 | * and overrule HWMP path selection algorithm. | |
77f576de T |
3971 | * @set_tid_config: TID specific configuration, this can be peer or BSS specific |
3972 | * This callback may sleep. | |

4318 | * on wiphy_new(), but can be changed by the driver if it has a good | |
4319 | * reason to override the default | |
9bc383de | 4320 | * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station |
33d915d9 MP |
4321 | * on a VLAN interface). This flag also serves an extra purpose of |
4322 | * supporting 4ADDR AP mode on devices which do not support AP/VLAN iftype. | |
9bc383de | 4323 | * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station |

4334 | * @WIPHY_FLAG_TDLS_EXTERNAL_SETUP: The device does not handle TDLS (802.11z) | |
4335 | * link setup/discovery operations internally. Setup, discovery and | |
4336 | * teardown packets should be sent through the @NL80211_CMD_TDLS_MGMT | |
