Re: [PATCH] dma\ae4dma: added AMD user space DMA driver

[fengchengwen <fengchengwen@huawei.com>]

Hi,

This commit modify the test-dma-perf and rte_mempool.h, but I can't get useful info
from the commit log.

So I recommend you split it to multiple commits, each commit implements a small function,
and well doc in commit log, this will help reviewer better understand.

Thanks
