[dpdk-dev] [PATCH v2 0/3] vhost: handle memory hotplug for async vhost

[Cheng Jiang]

When the guest memory is hotplugged, the vhost application which
enables DMA acceleration must stop DMA transfers before the vhost
re-maps the guest memory.

This patch set is to provide an unsafe API to drain in-flight pkts
which are submitted to DMA engine in vhost async data path, and
notify the vhost application of stopping DMA transfers. And enable it
in vhost example.
