7df0743339 app/crypto-perf: support AES-CCM
According to the API, AES-CCM has special requirements
when setting IV and AAD fields.
The L2fwd-crypto app is updated to set the nonce (IV)
and AAD in the right positions in these two fields
(1 byte after start of IV field and 18 bytes after start
of AAD).

3657283172 cryptodev: clarify API for AES-CCM
AES-CCM algorithm has some restrictions when
handling nonce (IV) and AAD information.

As the API stated, the nonce needs to be place 1 byte
after the start of the IV field. This field needs
to be 16 bytes long, regardless the length of the nonce,
but it is important to clarify that the first byte
and the padding added after the nonce may be modified
by the PMDs using this algorithm.

Same happens with the AAD. It needs to be placed 18 bytes
after the start of the AAD field. The field also needs
to be multiple of 16 bytes long and all memory reserved
(the first bytes and the padding (may be modified by the PMDs).

Lastly, nonce is not needed to be placed in the first 16 bytes
of the AAD, as the API stated, as that depends on the PMD
used, so the comment has been removed.

bf9d6702ec app/crypto-perf: use single mempool
In order to improve memory utilization, a single mempool
is created, containing the crypto operation and mbufs
(one if operation is in-place, two if out-of-place).
This way, a single object is allocated and freed
per operation, reducing the amount of memory in cache,
which improves scalability.

c4f916e332 app/crypto-perf: support multiple queue pairs
Add support for multiple queue pairs, when there are
more logical cores available than crypto devices enabled.
For instance, if there are 4 cores available and
2 crypto devices, each device will have two queue pairs.

This is useful to have multiple logical cores using
a single crypto device, without needing to initialize
a crypto device per core.

96dfeb609b app/crypto-perf: add new PMD benchmarking mode
This patch adds a new benchmarking mode, which is intended for
microbenchmarking individual parts of the cryptodev framework,
specifically crypto ops alloc-build-free, cryptodev PMD enqueue
and cryptodev PMD dequeue.

It works by first benchmarking crypto operation alloc-build-free
loop (no enqueues/dequeues happening), and then benchmarking
enqueue and dequeue separately, by first completely filling up the
TX queue, and then completely draining the RX queue.

Results are shown as cycle counts per alloc/build/free, PMD enqueue
and PMD dequeue.

One new test mode is added: "pmd-cyclecount"
  (called with --ptest=pmd-cyclecount)

New command-line argument is also added:
  --pmd-cyclecount-delay-ms: this is a pmd-cyclecount-specific parameter
      that controls the delay between enqueue and dequeue. This is
      useful for benchmarking hardware acceleration, as hardware may
      not be able to keep up with enqueued packets. This parameter
      can be increased if there are large amounts of dequeue
      retries.

Don't write CSR tail until we processed enough TX descriptors.

To avoid crypto operations sitting in the TX ring indefinitely,
the "force write" threshold is used:
 - on TX, no tail write coalescing will occur if number of inflights
   is below force write threshold
 - on RX, check if we have a number of crypto ops enqueued that is
   below force write threshold that are not yet submitted to

Original commit assumes there is 1:1 mapping between physical device and
ethdev port, so that device name can be used per port instead of ethdev
name field.

But one physical device may have multiple ethdev ports and each port
needs its own unique name.

One issue reported here:

So reverting back the commit to continue using ethdev name field per

index and a sepcific flowtype(PCTYPE).It also provide the solution
of flush all configuration about queue region the above described.

0693877018 net/ixgbe: fix VFIO interrupt mapping in VF
When a VF port is bound to VFIO-PIC, only miscellaneous interrupt
is mapped to VFIO vector 0 in eth_ixgbevf_dev_init( ).
In ixgbevf_dev_start(), if previous VFIO interrupt mapping set in
eth_ixgbevf_dev_init( ) is not cleard, it will fail when calling
rte_intr_enable( ) tries to map Rx queue interrupt to other VFIO
vectors. This patch clears the VFIO interrupt mappings before
setting both miscellaneous and Rx queue interrupt mappings again
to avoid failure.

ca9d659718 net/ixgbe: fix Rx queue interrupt mapping in VF
When a VF port is bound to VFIO-PCI, miscellaneous interrupt is
mapped to MSI-X vector 0 and Rx queues interrupt are mapped to
other vectors in vfio_enable_msix( ). To simplify implementation,
all VFIO-PCI bound ixgbe VF Rx queue interrupts can be mapped in
vector 1. And as current igb_uio only support only one vector,
ixgbe VF PMD should use vector 0 for igb_uio and vector 1 for
VFIO-PCI. Without this patch, VF Rx queue interrupt is mapped
to vector 0 in register settings and mapped to VFIO vector 1
in vfio_enable_msix( ), and then all Rx queue interrupts will
be missed.
