app/crypto-perf: fix invalid latency for QAT

Fixes invalid latency result when using the performance application and
hardware QAT PMD. It occurred when the number of processed packets was
higher then the size of the internal QAT PMD ring buffer and the buffer
was overflowed.
Fixed by correcting the registration of the enqueued packets and freeing
memory space for not enqueued packets.

7 years agocryptodev: enable BPI for Cablelabs DOCSIS security spec
Pablo de Lara [Thu, 23 Feb 2017 14:02:55 +0000 (14:02 +0000)]
cryptodev: enable BPI for Cablelabs DOCSIS security spec

Extend the DPDK cryptodev API to enable processing of packets according
to the Baseline Privacy Interface Plus (BPI+) Specification described in
the security specification of the Cablelabs Data-over-Cable Service
Interface Specification (DOCSIS).

Brief summary of BPI+ symmetric cryptography requirements:
BPI+ cryptography uses a block cipher (AES-CBC/DES-CBC) to encrypt/decrypt
all the whole blocks in the packet. However the data length is not always
a block-multiple, so where there is a final block less than the full block
size this residual block requires special handling using AES-CFB/DES-CFB
mode. Similar special handling is specified where there is only one block,
smaller than the block size for the cipher. See spec for further details.
https://apps.cablelabs.com/specification/docsis-3-1-security-specification/

Two new elements are added to the enum rte_crypto_cipher_algorithm.
Note elements of this enum are actually a combination of an algorithm (AES,
3DES, etc) and mode (CBC, CTR, etc). The new DOCSISBPI mode is used to
convey to the PMD that the mode applied should be the specific combination
of CBC and CFB required by the DOCSIS Baseline Privacy Plus Spec.

Set the value of m->refcnt to 1, m->nb_segs to 1 and m->next
to NULL when the mbuf is stored inside the mempool (unused).
This is done in rte_pktmbuf_prefree_seg(), before freeing or
recycling a mbuf.

Before this patch, the value of m->refcnt was expected to be 0
while in pool.

The objectives are:

- to avoid drivers to set m->next to NULL in the early Rx path, since
  this field is in the second 64B of the mbuf and its access could
  trigger a cache miss

- rationalize the behavior of raw_alloc/raw_free: one is now the
  symmetric of the other, and refcnt is never changed in these functions.

To optimize the freeing of the segments, we try try to only update
