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. 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.
