This patch set adds support for Intel NTB device with Skylake platform. It is a raw device for allowing two hosts to communicate with each other and access the peer memory.
This patch set also provides a simple example to transmit a file between two hosts. But since there is no FIFO here, only support file which is no more than 4M. And will add FIFO in the future.
