wireless_dev 头文件

`wireless_dev`是Linux内核中的一个结构体，定义在`include/net/cfg80211.h`头文件中。该结构体用于表示一个无线网络设备。

以下是`include/net/cfg80211.h`头文件中`wireless_dev`结构体的定义：

struct wireless_dev {
    const char *name;
    struct net_device *netdev;

    /* 一些回调函数 */
    int (*change_mtu)(struct wireless_dev *wdev, int new_mtu);
    int (*set_mac_addr)(struct wireless_dev *wdev, const uint8_t *mac);
    int (*set_channel)(struct wireless_dev *wdev, struct cfg80211_chan_def *chandef);
    int (*set_bitrate_mask)(struct wireless_dev *wdev, struct cfg80211_bitrate_mask *mask);
    int (*add_key)(struct wireless_dev *wdev, enum nl80211_key_type key_type,
           const uint8_t *key, uint32_t key_len);
    int (*del_key)(struct wireless_dev *wdev, enum nl80211_key_type key_type,
           const uint8_t *key, uint32_t key_len);
    int (*set_default_mgmt_key)(struct wireless_dev *wdev, uint8_t *key, uint32_t key_len);
    int (*set_wiphy_params)(struct wireless_dev *wdev, uint32_t changed);
    int (*set_mesh_config)(struct wireless_dev *wdev, struct mesh_config *conf);
    int (*set_power_mgmt)(struct wireless_dev *wdev, bool enabled, int timeout);
    int (*set_cqm_rssi_config)(struct wireless_dev *wdev, struct cfg80211_cqm_rssi_config *config);
    int (*set_quiet)(struct wireless_dev *wdev, struct cfg80211_quiet *quiet);
    int (*set_ap_chanwidth)(struct wireless_dev *wdev, struct cfg80211_chan_def *chandef);
    int (*set_rekey_data)(struct wireless_dev *wdev, const uint8_t *kek, uint32_t kek_len,
              const uint8_t *kck, uint32_t kck_len,
              uint64_t replay_ctr);
    int (*set_noack_map)(struct wireless_dev *wdev, uint16_t noack_map);

    struct wireless_dev_p2p_info p2p;

    struct wiphy *wiphy;
    void *priv;
    struct cfg80211_registered_device *ieee80211_ptr;

    /* 一些设备状态 */
    atomic_t iftype;
    unsigned int mesh_id_len;
    uint8_t mesh_id[0];
};

该结构体中包含了一个网络设备的名称、对应的net_device结构体、一些回调函数、设备状态、P2P信息等。在无线网络驱动中，可以通过该结构体来管理无线网络设备。
