We used to reserve DPDK lcore 0 for non pmd operations, making it difficult to use core 0 for packet processing. DPDK 2.0 properly support non EAL threads with lcore LCORE_ID_ANY. Using non EAL threads for non pmd threads, we do not need to reserve any core for non pmd operations Signed-off-by: Daniele Di Proietto <diproiettod@vmware.com> Signed-off-by: Ethan Jackson <ethan@nicira.com> Acked-by: Ethan Jackson <ethan@nicira.com>
