[dpdk-dev] [PATCH v3 0/4] Add dual threading in QAT PMD

[Arek Kusztal <arkadiuszx.kusztal@intel.com>]

Remove the limitation whereby enqueue and dequeue must be
done in same thread.
The inflight calculation is reworked to be thread-safe for 2
threads - note this is not general multi-thread support, i.e
all enqueues to a qp must still be done in one thread and
all dequeues must be done in one thread, but enqueues and
dequeues may be in separate threads.
As the tail-coalescing feature is not
threadsafe it is removed first.
Additional option added is to set minumum enqueue burst
threshold which may help to reduce MMIO write occurances.

v3:
- added minimum threshold option
v2:
- clarified wording in docs

Arek Kusztal (1):
  crypto/qat: add minimum enq threshold to qat pmd

Fiona Trahe (3):
  common/qat: remove tail write coalescing feature
  common/qat: move max inflights param into qp
  common/qat: add dual thread support
