Subject: [PATCH v2 0/6] crypto: tcrypt: fix and add multi buf speed tests

The performance of some crypto tfm providers is affected by
the amount of parallelism possible with the processing.

We already had some support for speed test of multiple concurrent
requests, dubbed multi buffer, in ahash speed tests.

This patch set extends said support and add similar support for skcipher
and AEAD, as well as fixes some odd bugs discovered along the way.

It is noted that it is possible to consolidate some of the none multi
buffer speed test code better, but given that tcrypt as a whole is a
developer testing harness rather than production code, the value of
this activity seems questionable. Do let me know if you disagree.
