On CN10KA B0/CN10KB, CPT scatter gather format has modified
to support multi-seg in inline IPsec. Due to this CPT requires
new firmware and doesn't work with CN10KA0/A1 firmware. To make
HW works in backward compatibility mode or works with CN10KA0/A1
firmware, a bit(T106_MODE) is introduced in HW CSR.

This patch adds devlink parameter for configuring T106_MODE.
This patch also documents the devlink parameter under

Add a load_device_defaults() function pointer to struct
idxd_driver_data, which if defined, will be called when an idxd device
is probed and will allow the idxd device to be configured with default
values.

The load_device_defaults() function is passed an idxd device to work
with to set specific device attributes.

Also add a load_device_defaults() implementation IAA devices; future
patches would add default functions for other device types such as
DSA.

The way idxd device probing works, if the device configuration is
valid at that point e.g. at least one workqueue and engine is properly
configured then the device will be enabled and ready to go.

The IAA implementation, idxd_load_iaa_device_defaults(), configures a
single workqueue (wq0) for each device with the following default
values:

      mode     	        "dedicated"
      threshold		0
      size		Total WQ Size from WQCAP
      priority		10
      type		IDXD_WQT_KERNEL
      group		0
      name              "iaa_crypto"
      driver_name       "crypto"

Note that this now adds another configuration step for any users that
want to configure their own devices/workqueus with something different
in that they'll first need to disable (in the case of IAA) wq0 and the
device itself before they can set their own attributes and re-enable,
since they've been already been auto-enabled.  Note also that in order
for the new configuration to be applied to the deflate-iaa crypto
algorithm the iaa_crypto module needs to unregister the old version,
which is accomplished by removing the iaa_crypto module, and
re-registering it with the new configuration by reinserting the
iaa_crypto module.

The existing iaa crypto async support provides an implementation that
satisfies the interface but does so in a synchronous manner - it fills
and submits the IDXD descriptor and then waits for it to complete
before returning.  This isn't a problem at the moment, since all
existing callers (e.g. zswap) wrap any asynchronous callees in a
synchronous wrapper anyway.

This change makes the iaa crypto async implementation truly
asynchronous: it fills and submits the IDXD descriptor, then returns
immediately with -EINPROGRESS.  It also sets the descriptor's 'request
completion irq' bit and sets up a callback with the IDXD driver which
is called when the operation completes and the irq fires.  The
existing callers such as zswap use synchronous wrappers to deal with
-EINPROGRESS and so work as expected without any changes.

This mode can be enabled by writing 'async_irq' to the sync_mode
iaa_crypto driver attribute:

  echo async_irq > /sys/bus/dsa/drivers/crypto/sync_mode

Async mode without interrupts (caller must poll) can be enabled by
writing 'async' to it:

  echo async > /sys/bus/dsa/drivers/crypto/sync_mode

The default sync mode can be enabled by writing 'sync' to it:

  echo sync > /sys/bus/dsa/drivers/crypto/sync_mode

The sync_mode value setting at the time the IAA algorithms are
registered is captured in each algorithm's crypto_ctx and used for all
compresses and decompresses when using a given algorithm.

This patch registers the deflate-iaa deflate compression algorithm and
hooks it up to the IAA hardware using the 'fixed' compression mode
introduced in the previous patch.

Because the IAA hardware has a 4k history-window limitation, only
buffers <= 4k, or that have been compressed using a <= 4k history
window, are technically compliant with the deflate spec, which allows
for a window of up to 32k.  Because of this limitation, the IAA fixed
mode deflate algorithm is given its own algorithm name, 'deflate-iaa'.

With this change, the deflate-iaa crypto algorithm is registered and
operational, and compression and decompression operations are fully
enabled following the successful binding of the first IAA workqueue
to the iaa_crypto sub-driver.

when there are no IAA workqueues bound to the driver, the IAA crypto
algorithm can be unregistered by removing the module.

A new iaa_crypto 'verify_compress' driver attribute is also added,
allowing the user to toggle compression verification.  If set, each
compress will be internally decompressed and the contents verified,
returning error codes if unsuccessful.  This can be toggled with 0/1:

  echo 0 > /sys/bus/dsa/drivers/crypto/verify_compress

The default setting is '1' - verify all compresses.

The verify_compress value setting at the time the algorithm is
registered is captured in the algorithm's crypto_ctx and used for all
compresses when using the algorithm.
