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 low_level_init() to do the actual setup of the hardware.

This function should be passed as a parameter to netif_add().

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

(

void *

pvParameters

)

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

It uses the function low_level_input() that should handle 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

pv_parameters

the lwip network interface structure for this ethernetif.
