> 1) In the EAL initialization phase, invoke the function rte_eal_cpu_init

> parsing of EAL arguments.
>
> 2) In the function rte_eal_cpu_init():
> - to parse the set of all running logical cores on the machine, do not
> use the RTE_LCORE_FOREACH macro that considers the set of already
> detected cores...
> Instead, use a standard loop based on the RTE_MAX_LCORE constant.
> - explicitely set to ROLE_RTE the role of each detected logical core
> that is recorded in the EAL configuration, as all running cores are
> enabled by default.
>
> 3) In the function eal_parse_coremask(), update the "lcore_count" field
> of the EAL configuration with the effective number of logical cores
> that are set in the mask of enabled logical cores.
