MLD stands for multi-link device. Note that there are 45 * devices that do not support WiFi-7 or even WiFi 6E and yet use iwlmld, but 46 * the firmware APIs used in this driver are WiFi-7 compatible. 47 * 48 * In the architecture of iwlwifi, an op_mode is a layer that translates 49 * mac80211's APIs into commands for the firmware and, of course, notifications 50 * from the firmware to mac80211's APIs. An op_mode must implement the 51 * interface defined in iwl-op-mode.h to interact with the transport layer 52 * which allows to send and receive data to the device, start the hardware, 53 * etc... 54 */ 55 56 /** 57 * DOC: Locking policy 58 * 59 * iwlmld has a very simple locking policy: it doesn't have any mutexes. It 60 * relies on cfg80211's wiphy->mtx and takes the lock when needed. All the 61 * control flows originating from mac80211 already acquired the lock, so that 62 * part is trivial, but also notifications that are received from the firmware 63 * and handled asynchronously are handled only after having taken the lock. 64 * This is described in notif.c. 65 * There are spin_locks needed to synchronize with the data path, around the 66 * allocation of the queues, for example. 67 */ 68 69 /** 70 * DOC: Debugfs 71 * 72 * iwlmld adds its share of debugfs hooks and its handlers are synchronized 73 * with the wiphy_lock using wiphy_locked_debugfs. This avoids races against 74 * resources deletion while the debugfs hook is being used. 75 */ 76 77 /** 78 * DOC: Main resources 79 * 80 * iwlmld is designed with the life cycle of the resource in mind. The 81 * resources are: 82 * 83 * - struct iwl_mld (matches mac80211's struct ieee80211_hw) 84 * 85 * - struct iwl_mld_vif (matches macu80211's struct ieee80211_vif) 86 * iwl_mld_vif contains an array of pointers to struct iwl_mld_link 87 * which describe the links for this vif. 88 * 89 * - struct iwl_mld_sta (matches mac80211's struct ieee80211_sta) 90 * iwl_mld_sta contains an array of points to struct iwl_mld_link_sta 91 * which describes the link stations for this station 92 * 93 * Each object has properties that can survive a firmware reset or not. 94 * Asynchronous firmware notifications can declare themselves as dependent on a 95 * certain instance of those resources and that means that the notifications 96 * will be cancelled once the instance is destroyed. 97 */ 98 99 #define IWL_MLD_MAX_ADDRESSES 5 100 101 /** 102 * struct iwl_mld - MLD op mode 103 * 104 * @fw_id_to_bss_conf: maps a fw id of a link to the corresponding 105 * ieee80211_bss_conf. 106 * @fw_id_to_vif: maps a fw id of a MAC context to the corresponding 107 * ieee80211_vif.
