ntb: ntb perf tool
Providing raw performance data via a tool that directly access data from NTB w/o any software overhead. This allows measurement of the hardware performance limit. In revision one we are only doing single direction CPU and DMA writes. Eventually we will provide bi-directional writes. The measurement using DMA engine for NTB performance measure does not measure the raw performance of DMA engine over NTB due to software overhead. But it should provide the peak performance through the Linux DMA driver.
