Hi Fan,

Few more comments from me in-line below.
Also a generic question - docs also might also need to be updated? 
Apart from that and naming collisions - looks good overall.

Shouldn't ipsec-secgw also be updated?

As a generic one - all the drivers for session-less sessions assume that sess_mp is initialized with
DIM(sess_data[]) greater than their driver id.
It is a valid assumption, but should we add extra check in rte_cryptodev_queue_pair_setup()?

As Fiona pointed we have to use sess->nb_drivers here.

That's a change in the public API, np in general,
but I suppose needs to be documented (release notes?).

New function - needs experimental tag, I think.
