Based on the text I guess you need the following to create a session:
struct session_create {
struct virtio_crypto_sym_ctlhdr ctlhdr; /* OUT */
struct virtio_crypto_sym_session_op session_op; /* OUT */
struct virtio_crypto_sym_session_op_inhdr inhdr; /* IN */
};
Please show the full C struct so the spec is clear on how to lay out the
request. The same applies for other operations.

Virtqueues are always "bidirectional" so this sentence doesn't mean
anything. It can be dropped.
