I had a quick look and it looks like is limited only to gcm(aes). 
I would be more interested to have a generic interface that could do generic algorithm
suits like aes-cbc-hmac-sha1 also.
This also seems to work in a synchronous (send one and wait) mode, which is a not good
solution for HW accelerators, which I'm trying to enable.
Thanks,
