void forwarding_createRplOption	(	rpl_option_ht *	rpl_option,
		uint8_t	flags
	)

Create a RPL option.

Parameters

[out]	rpl_option	A pointer to the structure to fill in.
[in]	flags	The flags to indicate in the RPL option.

void forwarding_getNextHop	(	open_addr_t *	destination128b,
		open_addr_t *	addressToWrite64b
	)

Retrieve the next hop's address from routing table.

Parameters

[in]	destination128b	Final IPv6 destination address.
[out]	addressToWrite64b	Location to write the EUI64 of next hop to.

owerror_t forwarding_send_internal_RoutingTable	(	OpenQueueEntry_t *	msg,
		ipv6_header_iht *	ipv6_header,
		rpl_option_ht *	rpl_option,
		uint32_t *	flow_label,
		uint8_t	fw_SendOrfw_Rcv
	)

Send a packet using the routing table to find the next hop.

Parameters

[in,out]	msg	The packet to send.
[in]	ipv6_header	The packet's IPv6 header.
[in]	rpl_option	The hop-by-hop option to add in this packet.
[in]	flow_label	The flowlabel to add in the 6LoWPAN header.
[in]	fw_SendOrfw_Rcv	The packet is originating from this mote (PCKTSEND), or forwarded (PCKTFORWARD).

owerror_t forwarding_send_internal_SourceRouting	(	OpenQueueEntry_t *	msg,
		ipv6_header_iht *	ipv6_header
	)

Send a packet using the source rout to find the next hop.

Note: This is always called for packets being forwarded.

How to process the routing header is detailed in http://tools.ietf.org/html/rfc6554#page-9.

Parameters

[in,out]	msg	The packet to send.
[in]	ipv6_header	The packet's IPv6 header.
