6550abbac1 nvme: prefetch stailq before freeing pcie request
We will need to put the recently completed nvme_request
object on the qpair's STAILQ.  We don't reference any
real data from the nvme_request in the completion path
since we've already stashed the cb_fn and cb_arg in
the nvme_tracker.  But we will need to reference the
STAILQ_ENTRY to put it back in the qpair's STAILQ, so
prefetch that cacheline.

b3d884b700 nvme: assign qpair when req is allocated
There's no need to set this every time we allocate
a request.

While here, fix a typo near where we needed to modify
the unit test to remove the qpair assertion.

5f4e42b80b vhost: abstract vring call mechanism as it is transport-specific
vring notification mechanism is transport-specific.  At present, vhost
dataplane code in `lib/vhost/vhost.c` triggers guest notifications with
`eventfd_write()` system call. But this is an AF_UNIX specific
notification mechanism. This patch replaces `eventfd_write()` with the
existing generic `rte_vhost_vring_call()` function that is part of
DPDK's librte_vhost public API.

`rte_vhost_vring_call()` takes a vring_idx as an argument to associate
the `struct spdk_vhost_virtqueue` instance with the relevant `struct
vhost_virtqueue` instance. We introduce a new `vring_idx` field in
`struct spdk_vhost_virtqueue` to enable this association. This field is
initialized in `start_device()`. In addition, a stub for
`rte_vhost_vring_call()` is added in the vhost unit test file.

SPDK's internal `rte_vhost` copy will not be updated in order to support
the virtio-vhost-user transport. However, an `rte_vhost_vring_call()`
function is introduced in SPDK's `rte_vhost` in order to have a solid
API. This function is just a wrapper of `eventfd_write()`.

a5dfbc4daf nvme: zero request->submit_tick in allocation
Request may be submitted several times via nvme_qpair_submit_request
function, such as request in queued_req queue being re-submitted.

With enabling timeout feature, nvme_qpair_submit_request compares
request->submit_tick to zero to check if this is the first submission
for this request. If true, record submit_tick for this reuqest.

So request->submit_tick needs to be set zero in allocation.

2632229b9d nvme/perf: only call verify_io when md_size > 0
verify_io is a function pointer, so avoiding the
call altogether is beneficial.  We know that no
verification is possible if md_size == 0, so use
this to determine if the call should be made.

d09874f3a2 nvme: remove avx optimizations when copying command
Using AVX512 or AVX2 ends up being a small pessimization.
I think AVX works better for copies when there are
multiple cachelines to copy.  I see a 2-3% improvement
in high IOPs benchmarks when reverting to SSE.

there are multiple completions pending, we can prefetch

2) Paramiko connection error: TypeError: missing_host_key() missing 1 required positional argument: 'key'
The set_missing_host_key_policy call should take a class instance AutoAddPolicy(), instead of the class name.
3) JSON config file defines "rdma_ips" instead of "nic_ips"
4) Added result file location in the documentation
5) Added env variable for PYTHONPATH to documentation
6) config.json changed default rw to randrw instead of read

from RPC lib from ./spdk/scripts/* it had to be created

By expanding PYTHONPATH in autotest_common, now any python

First example of this is located in:

7140c2f710 test/bdevio: add perform_tests RPC
New RPC added specifically to the bdevio app.
It will launch all tests on all targets by default.
When optional parameter for bdev name provided is supplied
tests will be ran against just that bdev.
After finishing, the application will await another RPC.

stop_init_thread() and __run_ut_thread now pass json request.

Added separate test.py to not pollute rpc.py with custom RPC
just for the bdevio application.

Added '-w' argument to the bdevio app, so that instead
of performing the tests immidietly - it awaits RPC.
After a lot of changes to blockdev.sh, we might end up
removing this argument and just use it as default.

8a43cd27e6 test/autotest: update how config options are set in autotest
NOTE: pulling the vbdevcompress change into its own patch...

While enabling reduce testing in autotest a few issues were found
in autotest in that some options were being set based on the existence
of a header without checking the test flag, if one existed. Then at
the end of adding options, specific test flags were checked for 0 and
the configure updated to --without.  So, to make this easier to read,
the options are organized in sections and where there is a header
dependency as well as a test flag, both are chcekced at the same time.
