Hi Tetsuya,

This patch should probably be split with the config changes as the first patch of this patch set.
The #ifdef RTE_LIBRTE_EAL_HOTPLUG changes should be no longer necessary as they will have been taken care of in the earlier patches (v2-11, v2-12, v2-13).
Maybe the  /lib/librte_eal/bsdapp/eal/rte_eal_version.map changes could be moved to one of the earlier bsd patches?

Regards,

Bernard.
