Yes, in theory it should work with any device that supports
in-place SGL.
On practice, right now I am not aware about inline-crypto devices
that can support such feature.
So far, tested with lookaside-none device.

In fact, ipsec lib can be used by all 4 cases I believe.
Though as I udenstand for lookaside-proto and inline-proto
nothing need to be added/changed inside the lib
(as HW supposed to deal with it transparently).

Here is a separate patch series that adds fragmentation/reassembly
support into ipsec-secgw and updates test-scripts with new test-cases:

I found that unnecessary, meson seems to be able to figure out implicit dependencies itself.
Though if you strongly insist, I can add them.
