Since commit b91c67e5a693211862aa7dc3b78630b4e856c2af,
maximum number of cores is 128, which has increase
the total memory necessary for a rte_mempool structure,
as the per-lcore local cache has been doubled in size.
Therefore, eal_flags unit test was broken since it needed
to use more hugepages.

Changes in v2: Increased memory to 18MB, as that is the
actual minimum memory necessary (depending on the physical memory segments,
DPDK may need less memory)

Signed-off-by: Pablo de Lara <redacted>

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).

Applied

I think we should try to improve this test to be able to run it everywhere.

Thanks
