* Name: net_setup
|
|
*
|
|
* Description:
|
|
* This is called from the OS initialization logic at power-up reset in
|
|
* order to configure networking data structures. This is called prior
|
|
* to platform-specific driver initialization so that the networking
|
|
* subsystem is prepared to deal with network driver initialization
|
|
* actions.
|
|
*
|
|
* Actions performed in this initialization phase assume that base OS
|
|
* facilities such as semaphores are available but this logic cannot
|
|
* depend upon OS resources such as interrupts or timers which are not
|
|
* yet available.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* None
