Hi Dmitry,
there are certain constraints applying.

1. none of the DEB_DPDK maintainers has used this so it would be great
if you could provide a set of testcases to ensure things work.
2. furthermore we learned (the hard way) that enabling non default
enabled drivers break us often.
    This is due to them being exposed to way less testing and verification.
3. Also we here have the special case that if possible it has to work
with openssl 1.0 (Ubuntu) AND 1.1 (Debian)
    According to the docs currently it does only the former.

We can work on all of that, but at a slow pace.
You could request at DPDK upstream if they consider it stable enough
to be default enabled?
And you might also mention the multi-openssl version compatibility to
be a nice to have.
