Functions
int	lpc1768_eth_init (const uint8_t *mac)
	Initialize the EMAC peripheral and PHY.

int	lpc1768_eth_send (const iolist_t *iolist)
	Submit a frame for transmission.

int	lpc1768_eth_recv (void *buf, size_t max_len)
	Receive a frame from the RX ring.

void	lpc1768_eth_get_mac (uint8_t out[6])
	Read the currently programmed MAC address.

void	lpc1768_eth_set_mac (const uint8_t mac[6])
	Program a new MAC address.

bool	lpc1768_eth_link_up (void)
	Read the PHY link status (BMSR.LINK)

bool	lpc1768_eth_rx_pending (void)
	Return true if the RX ring contains at least one unconsumed frame.

int	lpc1768_eth_tx_status (void)
	Query the completion status of the most recent transmission.

void	lpc1768_eth_set_promiscuous (bool enable)
	Enable or disable promiscuous mode.

bool	lpc1768_eth_get_promiscuous (void)
	Return the current promiscuous mode setting.

void	lpc1768_eth_set_link_speed (uint16_t speed)
	Configure the MAC for a given link speed and duplex.

int	lpc1768_eth_start_auto_negotiation (void)
	Start PHY auto-negotiation.

void	lpc1768_eth_complete_auto_negotiation (void)
	Complete auto-negotiation and apply speed/duplex to the MAC.
