net6_echo_cb

typedef void(* net6_echo_cb) (const struct in6_addr *ip, uint16 seq, uint64 delta_us, uint8 hlim, const uint8 *data, size_t len)

ICMPv6 echo reply callback type.

Parameters

ip	The IPv6 address the reply is from.
seq	The sequence number of the packet.
delta_us	The time difference, in microseconds.
hlim	The hop limit value in the packet.
data	Any data in the packet.
len	The length of the data, in bytes.

net_icmp6_send_dest_unreach()

int net_icmp6_send_dest_unreach	(	netif_t *	net,
		uint8	code,
		const uint8 *	ppkt,
		size_t	psz )

Send a destination unreachable packet on the specified interface.

Parameters

net	The network device to use.
code	The type of message this is.
ppkt	The message that caused this error.
psz	Size of the original message.

Returns

0 on success, <0 on failure.

net_icmp6_send_echo()

int net_icmp6_send_echo	(	netif_t *	net,
		const struct in6_addr *	dst,
		uint16	ident,

Send a Neighbor Solicitation packet on the specified device.

Parameters

net	The network device to use.
dst	The destination address.
target	The target address.
dupdet	1 if this is for duplicate detection.

Returns

0 on success, <0 on failure.

net_icmp6_send_param_prob()

int net_icmp6_send_param_prob	(	netif_t *	net,
		uint8	code,
