Browse Source 
In Fedora release 28, plug in nvme device and run setup.sh,
the uevent is like this:
UDEV  [1060.112118] add      /devices/virtual/vfio/81 (vfio)
ACTION=add

Have tested several kernel versions such as v3.10, v4.10, v4.15, v4.19.
 We didn't see an event which is like this:
ACTION=add
DRIVER=vfio-pci
