Subject: [RFC PATCH 08/18] crypto: testmgr - add a chacha20poly1305 test case
Date:   Wed, 25 Sep 2019 18:12:45 +0200
Message-Id: <20190925161255.1871-9-ard.biesheuvel@linaro.org>

Precedence: bulk

Add a test case to the RFC7539 (non-ESP) test vector array that
exercises the newly added code path that may optimize away one
invocation of the shash when the assoclen is a multiple of the
Poly1305 block size.
