RNDIS Support

Functions
void	rndis_packetFilter (uint32_t newfilter)
	Set the packet filter - currently distinguishes between promiscuous mode and normal mode.
uint8_t	rndis_send_encapsulated_command (uint16_t wLength)
	Handles a "SEND ENCAPSULATED COMMAND" message.
void	rndis_send_interrupt (void)
	Send an interrupt over the interrupt endpoint to the host.
void	rndis_query_process (void)
	Function to handle a RNDIS "QUERY" command in the encapsulated_buffer.
void	rndis_set_process (void)
	Function to deal with a RNDIS "SET" command present in the encapsulated_buffer.
uint8_t	rndis_get_encapsulated_command (void)
	Handle "GET ENCAPSULATED COMMAND".
uint8_t	rndis_send_status (rndis_Status_t stat)
	Send a status packet back to the host.
uint8_t	rndis_send (uint8_t *senddata, uint16_t sendlen, uint8_t led)
	Send data over RNDIS interface, data is in uipbuf and length is uiplen.
void	rx_start_led (void)
	This will enable the RX_START LED for a period.
void	tx_end_led (void)
	This will enable the TRX_END LED for a period.
	PROCESS_THREAD (usb_eth_process, ev, data_proc)
	RNDIS Process.
uint8_t	usb_eth_send (uint8_t *senddata, uint16_t sendlen, uint8_t led)
	Sends a single ethernet frame over USB using appropriate low-level protocol (EEM or RNDIS)
Variables
const uint32_t OIDSupportedList[]	PROGMEM
	List of supported RNDIS OID's.
uint8_t	usb_eth_data_buffer [64]
	Temp data buffer when adding RNDIS headers.
uint8_t	usb_eth_data_buffer [64]
	Temp data buffer when adding RNDIS headers.
uint8_t	led1_timer
	Timers for LEDs.

PROCESS_THREAD	(	usb_eth_process	,
		ev	,
		data_proc
	)

RNDIS Process.

This is the link between USB and the "good stuff". In this routine data is received and processed by RNDIS, CDC-ECM, or CDC-EEM

uint8_t rndis_get_encapsulated_command

(

void

)

Handle "GET ENCAPSULATED COMMAND".

Returns:

True on success, false on failure.

This function assumes the message has already set up in the "encapsulated_buffer" variable. This will be done by the "SEND ENCAPSULATED COMMAND" message, which will trigger and interrupt on the host so it knows data is ready.

< Send data until necessary

< Check endpoint 0 size
