The function is already called "rte_lcore_id()" so there is no need to change it to make it an "lcore" function. That function has been around for a long time and is commonly used, so I'd prefer it not be changed unless it really is necessary. "rte_lcore_index" is a sufficiently different function name, in my opinion. The API documentation should clear up any confusion for the user anyway.
