If you are going back to the drawing board with in-kernel acceleration
for OpenVPN, I strongly suggest to:
a) either stick to one implementation, and use the library interface,
or use dynamic dispatch using the crypto API AEAD abstraction, which
already implements 96-bit nonces for ChaCha20Poly1305,
b) consider using Aegis128 instead of AES-GCM or ChaChaPoly - it is
one of the winners of the CAESAR competition, and on hardware that
supports AES instructions, it is extremely efficient, and not
encumbered by the same issues that make AES-GCM tricky to use.
We might implement a library interface for Aegis128 if that is preferable.
