Performance isn't looking too hot for the Linux Kernel Crypto API on my zen2:

cpython (bpo-47102-linux-kcapi)$ ../b/python -m timeit -s 'import hashlib,hmac; d = b"0 1 2 3 5 2"*1000000; ksha2 = hashlib._LinuxKCAPIHash("sha256"); sha2 = hashlib.sha256(); h = sha2' 'h.update(d)'
50 loops, best of 5: 5.24 msec per loop
cpython (bpo-47102-linux-kcapi)$ ../b/python -m timeit -s 'import hashlib,hmac; d = b"0 1 2 3 5 2"*1000000; ksha2 = hashlib._LinuxKCAPIHash("sha256"); sha2 = hashlib.sha256(); h = ksha2' 'h.update(d)'
10 loops, best of 5: 38.6 msec per loop

the socket based kernel crypto API is 7x slower than OpenSSL.
