> Subject: [PATCH v9 0/6] rawdev driver for ntb
> 
> 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.
