[dpdk-dev] [PATCH v3 03/10] drivers/crypto: move aesni-mb PMD to IPsec-mb framework

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

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

This patch removes the crypto/aesni_mb folder and gathers all
aesni-mb PMD implementation specific details into a single file,
pmd_aesni_mb.c in crypto/ipsec_mb.

Now that intel-ipsec-mb v1.0 is the minimum supported version, old
macros can be replaced with the newer macros supported by this version.

Signed-off-by: Piotr Bronowski <piotrx.bronowski@intel.com>
Signed-off-by: Ciara Power <ciara.power@intel.com>

---
v3:
  - Updated intel-ipsec-mb library macros.
  - Fixed some formatting.
v2: Updated maintainers file.
