Is there an easy way for a driver get a pcie device removed
(as in echo 1 > /sys/devices/pcixxx/xxxx/remove)
and then force a rescan of the bus?
Clearly it could ask a daemon to do it - but finding the
correct entry in /sys/devices isn't entirely trivial.
(Or rather I don't know the trival way... )
The initial trigger would be a read returning ~0u.
But other things can be done to confirm the error.
eg: Reading config space and getting all zeros for the BARs
indicating that the endpoint has reset itself.
