In the fun game of what ifs...
The cmdline starts w/ device A placed at pci bus addr 00:04.0 (so
matched on source and target). The source does hotunplug of 04.0 and
replaces it w/ new device. I think we need something that is more
uniquely identifying the block. Not sure that device name is correct or
a generation ID.
