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.

Xiaoyun Li (6):
  raw/ntb: introduce ntb rawdev driver
  raw/ntb: add intel ntb support
  raw/ntb: add handshake process
  examples/ntb: enable an example for ntb
  usertools/dpdk-devbind.py: add support for ntb
  doc: update docs for ntb pmd
