Send the given NVM I/O command, I/O buffers, lists and all to
the NVMe controller.
This is a low level interface for submitting I/O commands directly.
This can only be used on PCIe controllers and qpairs.
This function allows a caller to submit an I/O request that is
COMPLETELY pre-defined, right down to the "physical" memory buffers.
It is intended for testing hardware, specifying exact buffer location,
alignment, and offset. It also allows for specific choice of PRP
and SGLs.
The driver sets the CID. EVERYTHING else is assumed set by the caller.
Needless to say, this is potentially extremely dangerous for both the host
(accidental/malicionus storage usage/corruption), and the device.
Thus its intent is for very specific hardware testing and environment
reproduction.

This is an attempt to fix device hotremove with VFIO.
A soft device hotremove request through sysfs [1] would
currently just block until the SPDK process manually
releases that device - e.g. upon an RPC request.
VFIO won't get unbound from the device untill userspace
releases all its resources. VFIO can signal a pending
hotremove request by kicking any file descriptor provided
by the userspace - and DPDK does provide such descriptor -
but SPDK does not listen on it.
DPDK does offer handy API to listen and in this patch
we make use of it inside our env/pci layer. Within
a DPDK callback we set an internal per-device hotremove
flag, which upper-layer SPDK drivers can poll with a new
env API - spdk_pci_device_is_removed().
The VFIO hotremove event will be sent to primary
processes only, so that's where we listen.
We make use of this new API in the NVMe hotplug poller,
which will process it just like any other supported
hotremove event.

However, some SPDK applications, e.g. nvme/perf, in addition
to using spdk_nvme_transport_id_parse() also check for the
existence of a "ns" key in the transport id string to limit

This patch disables the header digest and data digest
by default, which will improve the performance.
In the another patch, we will make it configurable.

Explicitly attaching a PCI device with spdk_pci_device_attach()
bypasses any kind of blacklists and should be only used
on a user request. Hotplug uevent is certainly not a user
request and should respect the blacklist, hence it's now
changed to call spdk_pci_enumerate() to probe new devices.
The enumeration callback will reject devices other that the
one we got hotplug request for, so no behavior is changed
in that matter.
This patch also fixes undefined behavior caused by reading
unitialized struct nvme_pcie_enum_cb;

It is the first patch to follow the NVMe over fabrics
spec and implmenent the NVMe/TCP transport. It can be
divided into work in the host and target sides:
Host side: Add the TCP/IP transport in nvme lib (lib/nvme).
Target side: Add the TCP/IP transport in nvmf lib (lib/nvmf).

Currently there are no timeout mechanism for Admin commands
when initialization, the NVMe driver may enter infinite loop.
While here, add a new parameter to the controller initialization
options, NVMe controller will report an error when timeout
happens during initialization.

The max_send_sge and max_recv_sge values can be set to any value from
0...dev_attr->max_sge. WHen we actually set the attributes, we will
receive a qpair with values for max_sge greater than or equal to what we
initially set. We need to store the maximum number of SGEs for later use
when constructing work requests.
Previously we have not relied on these values since we assumed that we
would always be able to have more sges than we asked for initially. This
may change as we try to allocate more SGEs to handle splitting buffers
across memory regions.

The RDMA memory map needs to be per-protection
domain, not per NVMe controller. Otherwise, when
an NVMe controller is removed, the memory map may
reference an invalid pointer to a detached
