The new format is: domain.bus.device.function

For this format, since we use '.' as separator,
to avoid misusing, we only support the following:

1 domain.bus.device.function ( 4 values provided)
2 bus.device.function  (3 values provoided with domain = 0)
3 bus.device  (2 values provided with domain = 0, function = 0)

13827a74a8 nvme: do not detach automatically on hot remove
The user's remove_cb should detach the NVMe controller when it can
ensure that it is no longer in use.  In the interim (between remove_cb
and spdk_nvme_detach()), the controller will remain in a failed state,
so any new I/O submissions will return an error code but not crash.

examples/nvme/hotplug is not yet updated for this change, but that will
be done in a separate patch.

0aec36be1f nvme: return virtual address in SGL callback
Instead of the next_sge callback returning the physical address
directly, make it return the virtual address and convert to physical
address inside the NVMe library.

This is necessary for NVMe over Fabrics host support, since the RDMA
userspace API requires virtual addresses rather than physical addresses.
It is also more consistent with the normal non-SGL NVMe functions that
already take virtual addresses.

fcb00f3780 nvme: expand probe information to a struct
spdk_nvme_probe() will now provide a struct spdk_nvme_probe_info to the
probe and attach callbacks in place of the PCI device pointer.

This struct contains the useful information that could be retrieved from
the PCI device during probe.

The goal of this change is to allow expansion of the probe information
in the future when other transports (specifically, NVMe over Fabrics)
are added that do not necessarily use PCI addressing or device IDs.

It's questionable whether "dataset" is valid English, but
it is best to match the specification.
