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

Detailed Description

Ethernet output for IPv6. Uses ND tables for link-layer addressing.

Function Documentation

◆ ethip6_output()

err_t ethip6_output ( struct netif netif,
struct pbuf q,
const 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, ask the ND6 module what to do. It will either let us send the the packet right away, or queue the packet for later itself, unless an error occurs.

Parameters
netifThe lwIP network interface which the IP packet will be sent on.
qThe pbuf(s) containing the IP packet to be sent.
ip6addrThe IP address of the packet destination.
Returns
