Typedef Documentation

typedef struct mpls_label_dpo_t mpls_label_dpo_t

A representation of an MPLS label for imposition in the data-path.

Function Documentation

u8* format_mpls_label_dpo	(	u8 *	s,
		va_list *	args
	)

Definition at line 100 of file mpls_label_dpo.c.

Here is the call graph for this function:

index_t mpls_label_dpo_create	(	mpls_label_t *	label_stack,
		mpls_eos_bit_t	eos,
		u8	ttl,
		u8	exp,
		dpo_proto_t	payload_proto,
		const dpo_id_t *	dpo
	)

Create an MPLS label object.

Parameters

label_stack	The stack if labels to impose, outer most label first
eos	The inner most label's EOS bit
ttl	The inner most label's TTL bit
exp	The inner most label's EXP bit
payload_proto	The ptocool of the payload packets that will be imposed with this label header.
dpo	The parent of the created MPLS label object

Here is the caller graph for this function:

STATIC_ASSERT	(	(sizeof(mpls_label_dpo_t)<=CLIB_CACHE_LINE_BYTES)	,
		"MPLS label DPO is larger than one cache line."
	)

Assert that the MPLS label object is less than a cache line in size.

Should this get any bigger then we will need to reconsider how many labels can be pushed in one object.
