Each ocf session is setup with the auth/enc paramaters.
The OCF crypto drivers then process that the best they can.  Currently
all the HW drivers do it in a single operation while the software crypto
driver "cryptosoft" does it individually.

The best place to look is in ipsec_ocf.c in ipsec_ocf_sa_init you will see
how it sets up a single session with auth, auth/enc or just enc.
