> Subject: [PATCH v3 2/7] service cores: EAL init changes
> X-Mailer: git-send-email 2.7.4
>
> This commit shows the changes required in rte_eal_init()
> to transparently launch the service threads. The threads
> are launched into the service worker functions here because
> after rte_eal_init() the application is not gauranteed to
> call any other DPDK API.
>
> As the registration of services happens at initialization
> time, the services that require CPU time are already available
> when we reach the end of rte_eal_init().

Not included this header file for bsdapp compilation. It should fail to
compile. Right?
