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.
v5:
* Actual v4. v4 patchset is the same as v3.
v4:
* Fix compile issues of comparison of array with null pointer.
v3:
* Fixed compilation issues with target i686.
* Renamed communication devices to misc devices in usertool.
* Rebased to the newest dpdk-next-net-intel branch.
v2:
* Replaced ! with NULL check for pointers.
* Added ntb_ops valid check before use it.
* Replaced RTE_MEMZONE_1GB with RTE_MEMZONE_IOVA_CONTIG in case users do
not use 1G hugepage.
* Added a timeout for dev_stop handshake in case that the peer stopped
abnormally such as crashed while debugging.
* Updated docs especailly about how to setup BIOS for skylake.
* Fixed not return issue and not free issue in example.
* Renamed ntb_devices to communication_devices to be more generic in
usertools.
* Polish the codes and docs.
