[openssl-users] Changing IV in EVP API?

While trying to convert some 3rd party code from direct calls
to libcrypto functions to using the EVP API, I have run into
I cannot find the EVP call to change the IV without changing
(and reexpanding) the key.
If the code should stay in the old (non-EVP) API, I similarly
lack a way to call the CPU optimized AES functions (AESNI,
HWAES, BSAES, VPAES) in the shared libcrypto.so .
Seems there is no way to win?
But I thought TLS 1.2 still needed the ability to efficiently
change IV mid-stream?
This is not GCM with its strange TLS specific IV formulas.
