+ * Some notes about how inet (currently only tcp) works on OSE.
+ * The driver uses OSE signals to communicate with the one_inet
+ * process. Because of the difference in how signals and file descriptors
+ * work the whole select/deselect mechanic is very different.
+ * 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.
+ * later when the function returns the new desired state is compared
+ * to the previous state and the apprioriate actions are taken. The action
+ * is usually to either request more data from the stack or stop requesting
+ * data.
+ *
+ * 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
+ * * tcp_inet_drv_output_ose : ready output callback, reads signals and calls
+ * dispatch_signal
+ * * tcp_inet_drv_input_ose : ready input callback.
