8f36853a84 dpdk_cryptodev: Check queue capacity before submitting a task
When we submit more tasks than supported by qp,
extra tasks are queued on io_channel. Later completion
poller tries to resubmit these tasks one by one. That
is not efficient since every enqueu_burst may cause
doorbell updates in HW.

Instead add a check for qpir capacity and submit
appropriate number of requests. If qpair is full,
tasks are queued in dedicated list. This approach
should remove or minimize the need to resubmit
individual crypto operations.

This also handles a case where there are no entries
in global pools (crypto_ops or rte_mbuf)

Fixes issue #2756

bf8e0656e8 dpdk_cryptodev: Remove limit on max IO size
Previously vbdev_crypto used DPDK directly and
the restriction on max IO size was propagated to
generic bdev layer which split big IO requests.

Now, when DPDK code is a standalone accel module,
this restriction on max IO size is not visible to
the user and we should get rid of it.

To remove this limitation, allow to submit crypto
operations for part of logical blocks in big IO,
the rest blocks will be processed when all submitted
crypto ops are completed.

To verify this patch, add a functional test which
submits big IO verify mode

957076108f accel: remove nbytes from spdk_accel_task
All operations are using iovecs to describe their buffers and only
encrypt/decrypt additionally used nbytes to store the total size of a
src buffer.  We don't really need this value in the generic accel code,
so we can let modules calculate it, if necessary.  That way, we won't
waste cycles calculating it if a module doesn't use it and it makes the
code a bit easier, as we won't have to deal with the fact that nbytes is
only valid for certain operations.

61fbb000fe module/accel: Add accel_dpdk_cryptodev
The new module replaces functionality in vbdev_crypto.
This module is bdev agnostic, so some inernal parts
were reworked.

io_channel: contains a qp of every configured DPDK PMD
crypto key: for mlx5_pci we register a key on each available
device since keys are bound to Protection Domain.

corresponding UT file. It makes it easier to review
the next patch which adds accel operations
