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_stackThe stack if labels to impose, outer most label first
eosThe inner most label's EOS bit
ttlThe inner most label's TTL bit
expThe inner most label's EXP bit
payload_protoThe ptocool of the payload packets that will be imposed with this label header.
dpoThe parent of the created MPLS label object

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.
