When DPDK is compiled with openssl 3.0. I am seeing these errors in compilation.
So, compilation is broken and we cannot take this patch as is.
We have few options,
- fix all of these errors,
- add exception in meson.build for ignoring these errors.
- disable/skip compilation of PMDs if openssl version is >3.0

Adding only one type of APIs does not make sense, if the driver is not compiled.
