This above dumps show that the actual output IV is indeed the input IV.
This is due to the IV not being copied back into the request.
This patch fixes that.

It's missing a Fixes: tag and a Cc: to stable.
I'll resend tomorrow.
While here, could you please check ecb mode (which by definition does not have
an IV) is behaving correctly?
Looking in driver_algs[] list of crypto algorithms supported by talitos,
ecb(aes,des,3des) are declared with ivsize != 0.
According to /proc/crypto, test are passed for ecb.
