[RFC 0/3] VirtIO RDMA
Data center backends use more and more RDMA or RoCE devices and more and
more software runs in virtualized environment.
There is a need for a standard to enable RDMA/RoCE on Virtual Machines.
Virtio is the optimal solution since is the de-facto para-virtualizaton
technology and also because the Virtio specification
allows Hardware Vendors to support Virtio protocol natively in order to
achieve
