inlinestatic

Determine the next L2 node based on the output feature bitmap.

Here is the call graph for this function:

Here is the caller graph for this function:

u32 l2output_create_output_node_mapping	(	vlib_main_t *	vlib_main,

		u32	node_index,
		u32 *	output_node_index_vec,
		u32	sw_if_index
	)

The next set of functions is for use by output feature graph nodes.

When the last bit has been cleared from the output feature bitmap, the next node is the output graph node for the TX sw_if_index. These functions help the feature nodes get that node index.

The next set of functions is for use by output feature graph nodes.
