Receive pipe reduces number of system calls and gives significant
performance improvement with kernel TCP stack and relatively small IO
sizes. With user space TCP/IP implementations there are no system

Bdev underneath lvs has a certain value set as block size,
then lvolstore inherits that as `io_unit_size`,
which ends up as block size for the lvol bdev presents.
Before this patch lvs on device with block size of 512,
would create lvol bdev with block size of 512.
Meanwhile reporting in bdev_lvol_get_lvstores(),
that block_size is 4k instead.
This was result of addition of io_unit_size and
forgetting to update the value here. Previously
only I/O of page_size was allowed.
This patch adjusts the value reported to
io_unit_size.
Alternatively it could have been removed,
or name changed to "io_unit_size".
Yet for API compatibility reason this name
remains.
Info on actual page size which is always 4k,
is not useful to bdev users. No need to add
another field for that.

The current thread tries aborting I/O command in the I/O qpair first.
If no I/O command to abort was found, send message to the thread which

aborting admin command in the admin qpair next. If no admin command
to abort was found, complete the abort request with failure.
spdk_nvme_ctrlr_cmd_abort_ext() is used to try aborting command whose
cb_arg matches. qpair is set to NULL when trying to abort admin command.
Before calling spdk_nvme_ctrlr_cmd_abort_ext(), save the current
thread to process admin command completion correctly.
spdk_bdev_abort() supports any bdev module other than NVMe bdev
module and does not check CDW0 but checks only if the completion
status is success or failure. So add bdev_nvme_abort_done() and
converts the NVMe completion status to the bdev completion status.

This patch only includes the basic framework for batching and the
ability to batch one type of command, copy. Follow-on patches will
add the ability to batch other commands and include an example of
how to do so via the accel perf tool. SW engine support for batching
will also come in a future patch. Documentation will also be coming.
Batching allows the application to submit a list of independent
descriptors to DSA with one single "batch" descriptor. This is beneficial
when the application is in a position to have several operations ready
at once; batching saves the overhead of submitting each one separately.
The way batching works in SPDK is as follows:
1) The app gets a handle to a new batch with spdk_accel_batch_create()
2) The app uses that handle to prepare a command to be included in the
batch. For copy the command is spdk_accel_batch_prep_copy(). The
app many continue to prep commands for the batch up to the max via
calling spdk_accel_batch_get_max()
3) The app then submits the batch with spdk_accel_batch_submit()
4) The callback provided for each command in the batch will be called as
they complete, the callback provided to the batch submit itself will be
called then the entire batch is done.

Add spdk_bdev_abort function as a new public API.
This goes all the way down to the bdev driver module and attempts to
abort all I/Os which has bio_cb_arg as its callback argument.
We can separate when only a single I/O has bio_cb_arg and when multiple
I/Os have bio_cb_arg, but unify both by using parent - children I/O
relationship. To avoid confusion, return matched_ios by _bdev_abort() and
store it into split_outstanding by the caller.
Exclude any I/O submitted after this abort command because the same cb_arg
may be used by all I/Os and abort may never complete.
bdev_io needs to have both bio_cb_arg and bio_to_abort because bio_cb_arg
is used to continue abort processing when it is stopped due to the capacity
of bdev_io pool, and bio_to_abort is used to pass it to the underlying
bdev module at submission. Parent I/O is not submitted directly, and is
only used in the generic bdev layer, and parent I/O's bdev_io uses bio_cb_arg.
Hence add bio_cb_arg to bdev structure and add bio_to_abort to abort structure.
In the meantime of abort operation, target I/Os may be completed. Hence
check if the target I/O still exists at completion, and set the completion
status to false only if it still exists.
Upon completion of this, i.e., this returned zero, the status
SPDK_BDEV_IO_STATUS_SUCCESS indicates all I/Os were successfully aborted,
or the status SPDK_BDEV_IO_STATUS_FAILED indicates any I/O was failed to
abort by any reason.
spdk_bdev_abort() does not support aborting abort or reset request
due to the complexity for now.
Following patches will support I/O split case.
Add unit tests together to cover the basic paths.
Besides, ABI compatibility check required us to bump up SO version of
a few libraries or modules. Bump up SO version of blob bdev module simply
because it does not have any out-of-tree consumer, and suppress bumping
up SO version of lvol library because the affected struct spdk_lvol
is not part of public APIs.

Patch below added writing out json configuration for accel modules.
(fad052b0) accel: add write_config json for accel modules
Out of two current modules, only idxd reported its confi out.
When idxd was not compiled in, then "framework_get_config accel"
RPC did not return a valid JSON. Following JSON was returned:
{\"jsonrpc\":\"2.0\",\"id\":1,\"result\":}
Where "result" never had any property given.
This patch adds array object to encompas all accel modules.
Next patch in series will try to address the issue on JSON
level.
