Although not very common and perhaps a bit strange, we do have users
that want to be able to hot plug/unplug virtio or vmxnet devices from
a running system, without shutting down the application nor the VM.

We have been enabling this in production for a year or so, so it's well
tested. The only issues found so far are fixed by this series.

Luca Boccassi (3):
  net/virtio: register/unregister intr handler on start/stop
  net/vmxnet3: fix vmxnet3 dev_uninit() hot-unplug
  eal/linux: handle uio read failure in interrupt handler
