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 540 of file ethernet_driver.c.

ethernetif_input()

void ethernetif_input

(

void *

argument

)

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

Definition at line 483 of file ethernet_driver.c.

ethernetif_notify_conn_changed()

void ethernetif_notify_conn_changed

(

struct netif *

netif

)

Function called on ethernet interface link change.

Parameters

*netif

pointer to the network interface structure

See also

ethernet_driver.h for further information regarding this callback

Definition at line 214 of file net.c.

ethernetif_set_link()

void ethernetif_set_link

(

void *

argument

)

This function sets the netif link status.

Parameters

netif

the network interface

Return values

None

Definition at line 610 of file ethernet_driver.c.

sys_jiffies()

u32_t sys_jiffies

(

void

)

Returns the current time in milliseconds when LWIP_TIMERS == 1 and NO_SYS == 1.

Parameters

None

Return values

Time

Definition at line 587 of file ethernet_driver.c.

sys_now()

u32_t sys_now

(

void

)

Returns the current time in milliseconds when LWIP_TIMERS == 1 and NO_SYS == 1.

Parameters

None

Return values

Time
