[PATCH v1] crypto/ipsec_mb: add digest encrypted feature in AESNI_MB

[Brian Dooley]

AESNI_MB PMD does not support Digest Encrypted. This patch adds partial
support for this feature.

Some out-of-place tests are still failing.
Only some in-place tests are passing.
Working on adding support for this feature in v2.

I do not get it, what is the point of adding partial support.
It should be added when it is supported.
Also whenever, you add, add in documentation as well.

You cannot just send half cooked patches.

Apologies for this, This patch has a bit more work to do and should have been an RFC.
Confident that it can be completed for the release.

[PATCH v9 3/3] test/crypto: fix failing synchronous tests

[Brian Dooley]

Some synchronous tests are not supported for cpu crypto and need to be
skipped. This commit adds in extra skips for these tests.
