ed53cba059 nvme: normalize PCI addresses before comparing
Use the env abstraction PCI functions to compare PCI addresses so that
details like whether or not domain is specified or whether 0-padding is
present don't affect the comparison.

For example, 0000:01:00.0 should compare equal to 01:00.0.

4382434855 nvme/pcie: add memory barrier process completions
Because ppc64 has less strict memory ordering behaviour
than x86 we need to introduce a memory barrier when
polling for completions due to possible reordering
of tracker and cpl access.

ffee381d82 nvme: allow a minimum of 10 seconds for shutdown
Some devices may report a RTD3E time that is shorter than their actual
shutdown time in practice; force the timeout to be at least 10 seconds
to allow for a reasonable amount of shutdown time.

This doesn't add any extra delay for devices that do complete the
shutdown process within their reported RTD3E time, since we will return
as soon as the device reports that it is finished shutting down.

32bff28a25 nvme: use spdk_pci_device_claim() in nvme_pcie_ctrlr_construct
spdk_pci_device_claim() can be used to ensure only one process
at a time uses any given PCI device.  Previously this was only
used in the bdev_nvme driver - other apps like nvme/perf do
not use spdk_pci_device_claim() and could effectively rip out
the device from a running bdev-based app like the NVMe-oF target.

So instead of modifying all of the nvme apps, put this logic into
the core nvme driver instead so that all applications get the
benefit transparently.  Save the fd when the controller is constructed
and then close it when the controller is destructed to handle the
detach (including hotplug) cases.

6368d6c0f5 nvme: add new spdk_nvme_connect() API to directly attach the ctrlr
With this new API, callers can attach one specific ctrlr identified by
the transport ID directly along with optional ctrlr opts. If connecting
to multiple controllers, it is still suggested to use spdk_nvme_probe()
and filter the requested controllers with the probe callback.

Two primary use cases:
1) connecting to the NVMe-oF discovery controller
2) more straightforward way to connect a specific controller (avoiding
the probe callback)

A typical usage of this API with specific ctrlr_opts:
1. struct spdk_nvme_ctrlr_opts user_opts = {}
2. Call spdk_nvme_ctrlr_get_default_ctrlr_opts(&user_opts, sizeof(user_opts))
3. Modify the content of the initialized user_opts with user required value like
   user_opts.num_io_queues = 8
4. Call spdk_nvme_connect(&trid, &user_opts, sizeof(user_opts))

48b2e94f66 nvme/rdma: remove newlines from discovery strings
The Linux kernel NVMe-oF target can easily be misconfigured to report
newline-terminated strings from the discovery service, since its
parameters are set by echoing into sysfs files, and echo adds a newline
by default.

Newline characters are not allowed as part of the TRADDR and TRSVCID
fields, since they are defined as ASCII strings in the NVMe specification
sense, which limits the acceptable characters to the 0x20-0x7E range.

However, we can add a workaround for misconfigured targets with trailing
newlines that shouldn't impact any valid configurations.

13f8cf1536 nvme: add NVME_QUIRK_DELAY_AFTER_QUEUE_ALLOC
The VirtualBox emulated NVMe device will intermittently
hang on the first read/write command after an I/O
qpair has been allocated.  The frequency of the hang
diminishes if a delay is added after allocating the I/O
qpair - until it disappears completely with a 100us delay.
So add a quirk to insert this delay.

Note - the 100us delay was tested by running
the hello_world example app 50000 times.

ac9b92c853 nvme/rdma: Consolidate send_cq and recv_cq
The send completions must be processed prior to the
recv completions. However, if the completion queues
are separate this leaves a small window where
a send+recv completion arrive between polling
the send_cq and the recv_cq, resulting in the code
seeing the recv completion prior to the send
completion.

By combining the completion queues, this eliminates
any potential gap. The send completion will always
be processed before the recv completion.
