Functions
err_t	ethip6_output (struct netif *netif, struct pbuf *q, ip6_addr_t *ip6addr)

err_t ethip6_output	(	struct netif *	netif,
		struct pbuf *	q,
		ip6_addr_t *	ip6addr
	)

Resolve and fill-in Ethernet address header for outgoing IPv6 packet.

For IPv6 multicast, corresponding Ethernet addresses are selected and the packet is transmitted on the link.

For unicast addresses, ...

anycast addresses

Parameters

netif	The lwIP network interface which the IP packet will be sent on.
q	The pbuf(s) containing the IP packet to be sent.
ip6addr	The IP address of the packet destination.

Returns

• ERR_RTE No route to destination (no gateway to external networks), or the return type of either etharp_query() or etharp_send_ip().
