Hum, looks like something is broken in master, when capturing packets:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7f03c6d31700 (LWP 98102)]
bucket_dequeue_orphans (n_orphans=251, obj_table=0x14fe83a10,
bd=0x14fe006c0) at
/root/dpdk/drivers/mempool/bucket/rte_mempool_bucket.c:194
194                rc = rte_ring_dequeue(bd->shared_bucket_ring,

I will have to start with a clean environment, just in case I broke
something when switching ovs / dpdk build dirs.
But I don't have the time now, maybe next week.
