Independently of RTE_MAX_LCORE being increased to 128, I still have some
problems with test_invalid_vdev_flag().
First, DEFAULT_MEM_SIZE is not used in this function.
Also, even with your patch, I get this error in my VM:
	Cannot get hugepage information

But if this patch solves an issue for you, I guess it should be applied.
That said, I would appreciate a complete description of the commands
you use to launch this test in a VM (starting with the Qemu command).

Thanks
