err_t ethernetif_init

(

struct netif *

netif

)

Should be called at the beginning of the program to set up the network interface.

It calls the function gmac_low_level_init() to do the actual setup of the hardware.

Parameters

netif

the lwIP network interface structure for this ethernetif.

Returns

ERR_OK if the loopif is initialized. ERR_MEM if private data couldn't be allocated. any other err_t on error.

void ethernetif_input

(

struct netif *

netif

)

This function should be called when a packet is ready to be read from the interface.

It uses the function gmac_low_level_input() that handles the actual reception of bytes from the network interface. Then the type of the received packet is determined and the appropriate input function is called.

Parameters

netif

the lwIP network interface structure for this ethernetif.
