f6823c5907 rdma: add a flag for disabling srq.
There are cases where srq can be a detriment. Add a flag to allow users
to disable srq even if they have a piece of hardware that supports it.

f93b6fb0a4 bdev: defer unregister untill *all* descriptors are closed
We used to wait only for those descriptors which
specified the hotremove notification callback. The
bdev could've been removed before the descriptor
was closed and the subsequent spdk_bdev_close would
simply segfault.

This patch modifies spdk_bdev_unregister to always
wait for all descriptors to be closed before actually
unregistering the bdev. This consolidates the bdev
unregister behavior for descriptors with and without
the hotremove callback.

56d8b78576 lib/scsi: Make spdk_scsi_dev_destruct asynchronous
This is the end of the patch series. After this patch,
delete_target_node RPC will wait for the completion of
removal of the SCSI device and then free the iSCSI target.

SCSI device holds passed callback and calls it in free_dev().
free_dev() is ensured to be called after all iSCSI sessions
are closed. So iSCSI target resource can be freed safely
after that.

81523d9dd2 env/dpdk: register VFIO hotremove callback
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.

Fixes #595
Fixes #690

[1] # echo 1 > /sys/bus/pci/devices/<bdf>/remove

bfd1e46e6e bdev: deprecate spdk_vbdev_register
This API had good intentions, but as more complicated
use cases came up where base bdevs could come and go,
we've realized that the bdev layer will need another
mechanism to query bdev modules on these types of
relationships between a virtual bdev and its base
bdevs.  We removed all code related to tracking
the array of base bdevs a long time ago.

Change all existing callers to use spdk_bdev_register.
Document spdk_vbdev_register as deprecated for now,
and change its implementation to just call
spdk_bdev_register for simplicity sake.

SPDK iSCSI target didn't convert LUN ID from integer to structure
when it sends R2T PDUs. The next patch will fix the issue. Introducing
helper functions into SCSI library and using them will be clean. Hence
this patch adds two helper functions to convert LUN ID between structure

The logic of helper functions is derived simply from the current
implementation in SPDK.

addressed by offsetting just a single physical address.

Since DPDK dynamic memory management came along, the
above is no longer true. Memory returned from spdk_*malloc()
doesn't have to be physically contiguous anymore. The
phys_addr returned from spdk_*malloc() only applies to
the beginning of the allocated buffer and user can't
possibly know how big that "beginning" is.

The phys_addr parameter in spdk_*malloc() is useless on
its own in most cases and only suggests that the returned
buffer is physically contiguous, which is wrong.

This information can be returned from spdk_vtophys(),
which is the only safe way to retrieve physical addresses.
That's why phys_addr param in spdk_*malloc() is now
deprecated.

ed0b611fc5 nvmf/rdma: Add shared receive queue support
This is a new feature for NVMEoF RDMA target, that is intended to save
resource allocation (by sharing them) and utilize the
locality (completions and memory) to get the best performance with
Shared Receive Queues (SRQs). We'll create a SRQ per core (poll
group), per device and associate each created QP/CQ with an
appropriate SRQ.

Our testing environment has 2 hosts.
Host 1:
  CPU: Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz dual socket (8 cores total)
  Network: ConnectX-5, ConnectX-5 VPI , 100GbE, single-port QSFP28, PCIe3.0 x16
  Disk: Intel Optane SSD 900P Series
  OS: Fedora 27 x86_64
Host 2:
  CPU: Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz dual-socket (24 cores total)
  Network: ConnectX-4 VPI , 100GbE, dual-port QSFP28
  Disk: Intel Optane SSD 900P Series
  OS : CentOS 7.5.1804 x86_64
Hosts are connected via Spectrum switch.
Host 1 is running SPDK NVMeoF target.
Host 2 is used as initiator running fio with SPDK plugin.

Configuration:
- SPDK NVMeoF target: cpu mask 0x0F (4 cores), max queue depth 128,
  max SRQ depth 1024, max QPs per controller 1024
- Single NVMf subsystem with single namespace backed by physical SSD disk
- fio with SPDK plugin: randread pattern, 1-256 jobs, block size 4k,
  IO depth 16, cpu_mask 0xFFF0, IO rate 10k, rate process “poisson”

Here is a full fio command line:
fio  --name=Job --stats=1 --group_reporting=1 --idle-prof=percpu \
--loops=1 --numjobs=1 --thread=1 --time_based=1 --runtime=30s \
--ramp_time=5s --bs=4k --size=4G --iodepth=16 --readwrite=randread \
--rwmixread=75 --randrepeat=1 --ioengine=spdk --direct=1 \
--gtod_reduce=0 --cpumask=0xFFF0 --rate_iops=10k \
--rate_process=poisson \
--filename='trtype=RDMA adrfam=IPv4 traddr=1.1.79.1 trsvcid=4420 ns=1'

SPDK allocates the following entities for every work request in
receive queue (shared or not): reqs (1024 bytes), recvs (96 bytes),
cmds (64 bytes), cpls (16 bytes), in_capsule_buffer. All except the
last one are fixed size. In capsule data size is configured to 4096.
Memory consumption calculation (target):
- Multiple SRQ: core_num * ib_devs_num * SRQ_depth * (1200 +
  in_capsule_data_size)
- Multiple RQ: queue_num * RQ_depth * (1200 + in_capsule_data_size)
We ignore admin queues in calculations for simplicity.

Cases:
1. Multiple SRQ with 1024 entries:
   - Mem = 4 * 1 * 1024 * (1200 + 4096) = 20.7 MiB
     (Constant number – does not depend on initiators number)
2. RQ with 128 entries for 64 initiators:
   - Mem = 64 * 128 * (1200 + 4096) = 41.4 MiB

Results:
