Subject: how to verify which crypto driver is loaded by crypto_alloc_shash
 when more than one available for the algorithm

Was trying to see which driver was loaded by:

   crypto_alloc_shash(hmac(md5), ...);

and it was confusing because it looked like there were at least five
drivers that export that cra_name (most presumably hardware specific),
so was wondering what is the "default" that would be chosen and how to
tell which of the five ended up being used.
