This driver exists to allow the user to have an Ethernet interface on
top of a high-speed InfiniBand (IB) interconnect.
Users would like to use sockets API from the VM without re-writing their
applications on top of IB verbs, this driver meant to allow such a user
to do so.
Exposing IB emulators and having IB support in the management tools for
the VM/Hypervisor won't address the usecases that this driver meant for.
With this driver, existing VMs, and their existing IP applications, can
run as-is on InfiniBand network.
