Function Documentation

gnrc_sixlowpan_dispatch_recv()

void gnrc_sixlowpan_dispatch_recv	(	gnrc_pktsnip_t *	pkt,
		void *	context,
		unsigned	page
	)

Delegates a packet to the network layer.

Parameters

[in]	pkt	A packet
[in]	context	Context for the packet. May be NULL.
[in]	page	Current 6Lo dispatch parsing page

gnrc_sixlowpan_dispatch_send()

void gnrc_sixlowpan_dispatch_send	(	gnrc_pktsnip_t *	pkt,
		void *	context,
		unsigned	page
	)

Delegates a packet to the network interface.

Parameters

[in]	pkt	A packet
[in]	context	Context for the packet. May be NULL.
[in]	page	Current 6Lo dispatch parsing page

gnrc_sixlowpan_get_pid()

kernel_pid_t gnrc_sixlowpan_get_pid

(

void

)

Returns the PID of the 6Lo thread.

Returns

The PID of the 6Lo thread on success

KERNEL_PID_UNDEF, when 6Lo thread was not started.

gnrc_sixlowpan_multiplex_by_size()

void gnrc_sixlowpan_multiplex_by_size	(	gnrc_pktsnip_t *	pkt,
		size_t	orig_datagram_size,
		gnrc_netif_t *	netif,
		unsigned	page
	)

Checks if packet fits over interface (and fragments if 6LoWPAN Fragmentation is available and required)

Parameters

[in]	pkt	The packet to fit. Must not be NULL.
[in]	orig_datagram_size	The original (uncompressed) datagram size.
[in]	netif	The interface to fit pkt over. Must not be NULL.
[in]	page	Current 6Lo dispatch parsing page
