Using OpenSSL with Devcrypto in async mode

Hi All,
This is my first time sending mail to a mailing list, thus if the message
is not in the correct format my apology.

I'm using OpenSSL together with Devcrypto in order to utilize crypto
hardware acceleration.
I just found that Devcrypto has an asynch mode in which it's queueing the
crypto requests received from userspace.

I wonder whether OpenSSL can work with Devcrypto in async mode. From a
short research of the source code, seems like it's not - Devcrypto requires
a "special" ioctl commands for async operations (CIOCASYNCCRYPT,
CIOCASYNCFETCH)which are not exist in e_devcrypto.c

Many thanks, Liad
