i.MX6DQ HDMI 加密狗板使用 BCM4330（SDIO 接口）作为无线模块。
当我们尝试在 HDMI 加密狗板上运行 Ubuntu oneiric 时，在正确 insmod bcm4330.ko 之后，我们发现 Ubuntu NetworkManger 无法识别该接口：/var/log/syslog 显示以下错误：
1 月 1 日 00:01:08 linaro-ubuntu-desktop NetworkManager[4787]: SCPlugin-Ifupdown: 已添加设备（路径：/sys/devices/virtual/net/wlan0，iface：wlan0）
Jan 1 00:01:08 linaro-ubuntu-desktop NetworkManager[4787]：SCPlugin-Ifupdown：已添加设备（路径：/sys/devices/virtual/net/wlan0，iface：wlan0）：未找到 ifupdown 配置。
1 月 1 日 00:01:08 linaro-ubuntu-desktop NetworkManager[4787]:
经过Google搜索，我们发现/sys/devices/virtual/net/wlan0目录下并没有“device”目录，这个“device”目录应该是网络接口上存在的，如果没有它，NetworkManager会报错“couldn't determine device driver; ignoring...”，这个“device”就是这个网络接口的来源，它应该链接到一个硬件总线下的真实设备。
而Broadcom的bcm4330 Linux驱动程序没有设置网络接口真正的“设备”，所以我们需要在驱动程序注册网络接口之前添加这个真正的“设备”。
