+ * interface changes. This happens when a bpf device attaches to an
+ * interface or detaches from an interface. The tap mode will join
+ * together (bit or) the modes of all bpf devices using that
+ * interface for that dlt. If you return an error from this
+ * function, the bpf device attach attempt that triggered the tap
+ * will fail. If this function was called bacuse the tap state was
+ * decreasing (tap in or out is stopping), the error will be
+ * ignored.
+ * @param interface The interface being tapped.
+ * @param data_link_type The data link type being tapped.
