void vnet_config_update_feature_count ( vnet_feature_main_t fm,
u8  arc,
u32  sw_if_index,
int  is_add 
)
static_always_inline int vnet_device_input_have_features ( u32  sw_if_index)

Definition at line 243 of file feature.h.

+ Here is the call graph for this function:

+ Here is the caller graph for this function:

clib_error_t* vnet_feature_arc_init ( vlib_main_t vm,
vnet_config_main_t vcm,
char **  feature_start_nodes,
int  num_feature_start_nodes,
vnet_feature_registration_t first_reg,
char ***  in_feature_nodes 
)

Initialize a feature graph arc.

Parameters
vmvlib main structure pointer
vcmvnet config main structure pointer
feature_start_nodesnames of start-nodes which use this feature graph arc
num_feature_start_nodesnumber of start-nodes
first_regfirst element in [an attribute((constructor)) function built, or otherwise created] singly-linked list of feature registrations
[out]in_feature_nodesreturned vector of topologically-sorted feature node names, for use in show commands
Returns
0 on success, otherwise an error message. Errors are fatal since they invariably involve mistyped node-names, or genuinely missing node-names
