This is a new vhost user protocol feature to better support the vDPA device at the vhost user backend. It allows interrupts/notifications being delivered between the driver in guest and the device in host directly. Dependencies: 1. This patch set depends on the below patch set for QEMU: http://lists.nongnu.org/archive/html/qemu-devel/2018-01/msg06028.html Some of the enum definitions in this patch set have been updated for the latest QEMU. A new patch set for QEMU will be sent out later. 2. This patch set depends on Zhihong's "selective datapath" patch set: http://dpdk.org/ml/archives/dev/2018-March/091858.html This patch set is generated on the latest master branch of dpdk-next-virtio with Zhihong's patches applied.
