/**

|
|
|
* @brief The Ethernet driver mainly consists of PHY, MAC and
|
|
|
|
* the mediator who will handle the request/response from/to MAC, PHY and Users.
|
|
|
|
* Ethernet driver adopts an OS timer to check the link status periodically.
|
|
|
|
* This structure preserves some important Ethernet attributes (e.g. speed, duplex, link).
|
|
|
|
* Function stack_input is the channel which set by user, it will deliver all received packets.
|
|
|
|
* If stack_input is set to NULL, then all received packets will be passed to tcp/ip stack.
|
|
|
|
* on_lowlevel_init_done and on_lowlevel_deinit_done are callbacks set by user.
|
|
|
|
* In the callback, user can do any low level operations (e.g. enable/disable crystal clock).

// Mediator functions need to find the right actor (MAC, PHY or user) to perform the operation.
