[dpdk-dev] [PATCH v4 10/14] drivers/crypto: move snow3g PMD to IPsec-mb framework

[Ciara Power <ciara.power@intel.com>]

From: Piotr Bronowski <piotrx.bronowski@intel.com>

This patch removes the crypto/snow3g folder and gathers all snow3g PMD
implementation specific details into a single file,
pmd_snow3g.c in the crypto/ipsec_mb folder.

Signed-off-by: Piotr Bronowski <piotrx.bronowski@intel.com>
Signed-off-by: Ciara Power <ciara.power@intel.com>
Acked-by: Ray Kinsella <mdr@ashroe.eu>

---
v4:
  - Removed extra empty lines.
  - Removed call to enqueue when processing ops, no longer needed.
  - Fixed some function names.
  - Removed unnecessary enqueued counts from process_ops function.
  - Added release note.
  - Removed security includes.
  - Split into private header file.
v3: Removed extra empty lines.
v2: Updated maintainers file.
