eal: fix vdev allocation on non-0 numa socket
vdev ethdev can not be allocated on a numa socket that is not socket 0. The reason comes from rte_eth_dev_allocate() which uses rte_socket_id() to identify the socket on which vdev driver data should be allocated. However, at this initialization step, rte_socket_id() always returns 0. Looking at rte_socket_id(), it needs rte_lcore_id() which uses the per-core global _lcore_id variable. This variable is initialised by eal_thread_init_master. So eal_thread_init_master should be called before rte_eal_vdev_init(). Signed-off-by: Maxime Leroy <> Acked-by: Thomas Monjalon <>
