err_t	bfeth_init (struct netif *netif)

Detailed Description

Barrelfish standard ethernet interface

Function Documentation

err_t bfeth_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 bfeth

Returns

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

void bfeth_input	(	struct netif *	netif,
		uint64_t	pbuf_id,
		uint64_t	paddr,
		uint64_t	len,
		uint64_t	packet_len,
		struct pbuf *	pp
	)

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 bfeth
