+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.
