commit: https://git.buildroot.net/buildroot/commit/?id=4b12336d1fad12fbb82b4d9144e6cb5636a12256
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

CONFIG_CRYPTO_AEAD2=y.

CONFIG_CRYPTO_AEAD2 and CONFIG_CRYPTO_SKCIPHER2 are needed to fix the
following build failure:

ERROR: modpost: "crypto_alloc_skcipher" [/home/autobuild/autobuild/instance-2/output-1/build/cryptodev-linux-1.12/./cryptodev.ko] undefined!

However, those options are not user-selectable. They are enabled by the
appropriate consumers of those cyphers. Since cryptodev is anyway meant
to give userspace access to kernel crypto (hardware), it makes sense to
enable CONFIG_CRYPTO. The easiest way to also get AEAD2 and SKCIPHER2 is
to enable CONFIG_CRYPTO_USER_API_AEAD as well.
