[PATCH v4] crypto/ipsec_mb: unified IPsec MB interface

[Akhil Goyal]

> Hi folks,
> 
> The introduction of a more unified IPsec MB library for DPDK is causing the
> snow3g tests to fail on ARM. Artifact here:
> https://lab.dpdk.org/results/dashboard/patchsets/29315/
> PMDs using the direct API (KASUMI, CHACHA, ZUC, SNOW3G) will use the job API,
> from the AESNI MB PMD code.
> We have come across a similar issue in the past that related to an offset issue as
> SNOW3G uses bits instead of bytes.

The above link does not seem to be working. 
I believe from now on, since we continue to maintain two separate repos,
it would be better to get ack from ARM folks as well
before merging anything onto crypto/ipsec_mb PMD.

Arm folks, Could you please get the below change tested/incorporated in the repo.
