Function Documentation

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

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

	vm	vlib main structure pointer
	vcm	vnet config main structure pointer
	feature_start_nodes	names of start-nodes which use this feature graph arc
	num_feature_start_nodes	number of start-nodes
	first_reg	first element in [an attribute((constructor)) function built, or otherwise created] singly-linked list of feature registrations
[out]	in_feature_nodes	returned 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
