+
+Routine Description:
+
+    This routine performs the TdiSetEventHandler request for the
+    transport provider.  The caller (request dispatcher) verifies
+    that this routine will not be executed on behalf of a user-mode
+    client, as this request enables direct callouts at DISPATCH_LEVEL.
+
+Arguments:
+
+    Device - The netbios device object.
+
+    Request - Pointer to the request.
+
+Return Value:
+
+    NTSTATUS - status of operation.
