Subject: eng_devcrypto: save ioctl if EVP_MD_..FLAG_ONESHOT
|
|
|
|
Since each ioctl causes a context switch, slowing things down, if
|
|
EVP_MD_CTX_FLAG_ONESHOT is set, then:
|
|
- call the ioctl in digest_update, saving the result; and
|
|
- just copy the result in digest_final, instead of using another ioctl.
