+ * In ose when a sock_select is done a function is called. That function
+ * notes the changes that the driver want to do, but does not act on it.

+ *
+ * One thing to note is that the driver never does select/deselect. It always
+ * listens for the signals. Flow of data is regulated by sending or not sending
+ * signals to the ose inet process.
+ *
+ * The interesting functions to look at are:
+ * * inet_driver_select : called when sock_select is called
+ * * tcp_inet_ose_dispatch_signal : checks state changes and sends new signals
