> As a result of moving tailq's into local memory, some tailq data
> is now reserved in rte_malloc heaps (because it needs to be
> shared across DPDK processes). The first thing DPDK initializes
> is a log mempool, and since it creates a tailq, it reserves
> space in rte_malloc heap before allocating the mempool itself.
> By default, rte_malloc allocates way more space than is necessary,
> so under some conditions (namely, overall memory available is low)
> this results in malloc heap eating up so much memory that log
> mempool is not able to allocate its memzone.
>
> This patch fixes the unit tests to account for that change.
