From: Zhu, Yi <yi.zhu@xxxxxxxxx> mac80211 supports multiple virtual interfaces for a single device. For example, a managed interface (wlan0) and a monitor interface (mon0) can exist at the same time. Thus priv->iw_mode is not sufficient to track the wireless mode any more. The patch redefines priv->iw_mode as the first interface mode (the same as priv->vif->type if priv->vif != NULL). If another monitor type interface is created later, we don't change priv->iw_mode into monitor. This way, the original interface still works. The patch also requests mac80211 to do reassociation after we change the Rx filter flags.
