Until now, all the traffic was blocked during scan operation. However, scan operation is going to be used to implement Remain On Channel (ROC). In this case, special frames (marked with IEEE80211_TX_CTL_TX_OFFCHAN) must be sent during the operation. These frames need to be sent on the virtual interface #2. Until now, this interface was only used by the device for internal purpose. But since API 3.9, it can be used to send data during scan operation (we hijack the scan process to implement ROC). Thus, we need to change a bit the way we match the frames with the interface. Fortunately, the frames received during the scan are marked with the correct interface number. So there is no change to do on this part.
