Function Documentation

ethernetif_init()

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

Definition at line 302 of file ethernetif.c.

Here is the call graph for this function:

ethernetif_input()

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 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

netif

the lwip network interface structure for this ethernetif
