[dpdk-dev] [PATCH v6 0/8] Introduce CPU crypto mode

[Marcin Smoczynski <marcinx.smoczynski@intel.com>]

Originally both SW and HW crypto PMDs use rte_crypot_op based API to
process the crypto workload asynchronously. This way provides uniformity
to both PMD types, but also introduce unnecessary performance penalty to
SW PMDs that have to "simulate" HW async behavior (crypto-ops
enqueue/dequeue, HW addresses computations, storing/dereferencing user
provided data (mbuf) for each crypto-op, etc).

The aim is to introduce a new optional API for SW crypto-devices
to perform crypto processing in a synchronous manner.

v3 to v4 changes:
 - add feature discovery in the ipsec example application when
   using cpu-crypto
 - add gmac in aesni-gcm
 - add tests for aesni-gcm/cpu crypto mode
 - add documentation: pg and rel notes
 - remove xform flags as no longer needed
 - add some extra API comments
 - remove compilation error from v3

v4 to v5 changes:
 - fixed build error for arm64 (missing header include)
 - update licensing information

v5 to v6 changes:
 - unit tests integrated in the current test application for cryptodev
 - iova fix
 - moved mbuf to sgl helper function to crypo sym header
