Per-channel NIC configuration. More...

#include <ra8_eth.h>

Data Fields
uint8_t	mac_address [6]
	Local MAC address (octets 0..5).
uint8_t	channel
	Logical channel index (0..1).
uint16_t	num_tx_descriptors
	Active TX descriptors (<=8, 0=def).
uint16_t	num_rx_descriptors
	Active RX descriptors (<=8, 0=def).
uint16_t	buffer_size
	Buffer size per descriptor.

Detailed Description

Per-channel NIC configuration.

Passed by const-pointer so future additions never break the ABI. num_tx_descriptors / num_rx_descriptors may be 0 to mean "use the compile-time defaults"; if non-zero they must satisfy 1 <= count <= k_ra8_eth_num_tx_desc / k_ra8_eth_num_rx_desc. buffer_size is similarly capped at k_ra8_eth_buf_size.
