rwnx_vif结构体中主要包含rwnx_hw硬件相关结构体（即mac层相关硬件结构体的描述）
和wireless_dev和网络层net_device及网络状态net_device_stats结构体。
nl80211_auth_type认证算法，sta和ap相关bssid即mesh组网描述。
rwnx_hw 则主要包含基类struct device *dev，sdio设备描述struct aic_sdio_dev *sdiodev或者
usb设备描述struct aic_usb_dev *usbdev，及无线phy设备描述struct wiphy *wiphy。
还有cfg80211扫描请求描述struct cfg80211_scan_request *scan_request，及工作任务描述
struct tasklet_struct task，如果使能CONFIG_USE_WIRELESS_EXT的话还有相关EXT的描述。
