- * 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.
