Function Documentation

bool copy_packet_to_user	(	struct buffer_descriptor *	buffer,
		void *	data,
		uint64_t	len,
		uint64_t	flags
	)

Used in combination with software filtering, to copy a packet into a user buffer.

void ethersrv_argument

(

const char *

arg

)

Pass command line argument not used by driver to library. Can be called multiple times, once for each parameter.

void ethersrv_init	(	char *	service_name,
		uint64_t	queueid,
		ether_get_mac_address_t	get_mac_ptr,
		ether_terminate_queue	terminate_queue_ptr,
		ether_transmit_pbuf_list_t	transmit_ptr,
		ether_get_tx_free_slots	tx_free_slots_ptr,
		ether_handle_free_TX_slot	handle_free_tx_slots_ptr,
		size_t	rx_buffer_size,
		ether_rx_register_buffer	rx_register_buffer_ptr,
		ether_rx_get_free_slots	rx_get_free_slots_ptr
	)

Initialize pair of ethernet RX/TX queues.

Parameters

service_name	Service name for the card to which this queue belongs
queueid	Queue index
get_mac_ptr	Callback that returns MAC address of the card
terminate_queue_ptr	Callback that terminates the queue driver, or NULL if this is not supported.
transmit_ptr	Callback to put a buffer chain in TX queue
tx_free_slots_ptr	Callback that returns number of free slots in TX queue
handle_free_tx_slots_ptr	Callback to remove transmitted buffers from queue
rx_buffer_size	Expected RX buffer size
rx_register_buffer_ptr	Callback to register buffer for RX queue
rx_get_free_slots_ptr	Callback that returns number of free slots in RX queue

void process_received_packet	(	struct driver_rx_buffer *	bufs,
		size_t	count,
		uint64_t	flags
	)

Called by driver when it receives a new packet.
