+     * like current country code, operational mode (e.g. STA, SAP, WFD-CLI,
+     * WFD-GO, TDLS, NAN) and other restrictons due to DFS, cellular coexistence
+     * and conncurency state of the device.

+     * @param ifaceModeMask Bitmask of the modes represented by |WifiIfaceMode|
+     *        Bitmask respresents all the modes that the caller is interested
+     *        in (e.g. STA, SAP, CLI, GO, TDLS, NAN). E.g. If the caller is
+     *        interested in knowing usable channels for P2P CLI, P2P GO & NAN,
+     *        ifaceModeMask would be set to
+     *        IFACE_MODE_P2P_CLIENT|IFACE_MODE_P2P_GO|IFACE_MODE_NAN.
+     * @param filterMask Bitmask of filters represented by
+     *        |UsableChannelFilter|. Specifies whether driver should filter
+     *        channels based on additional criteria. If no filter is specified
+     *        driver should return usable channels purely based on regulatory
+     *        constraints.
+     * @return status WifiStatus of the operation.
+     *         Possible status codes:
+     *         |WifiStatusCode.SUCCESS|,
+     *         |WifiStatusCode.ERROR_NOT_SUPPORTED|,
+     *         |WifiStatusCode.ERROR_INVALID_ARGS|,
+     *         |WifiStatusCode.FAILURE_UNKNOWN|
+     * @return channels List of channels represented by |WifiUsableChannel|
+     *         Each entry represents a channel frequency, bandwidth and
+     *         bitmask of modes (e.g. STA, SAP, CLI, GO, TDLS, NAN) that are
+     *         allowed on that channel. E.g. If only STA mode can be supported
+     *         on an indoor channel, only the IFACE_MODE_STA bit would be set
+     *         for that channel. If 5GHz SAP cannot be supported, then none of
+     *         the 5GHz channels will have IFACE_MODE_SOFTAP bit set.
+     *         Note: Bits do not represent concurrency state. Each bit only
+     *         represents whether particular mode is allowed on that channel.
