Can we remove these includes from here and add in test_pdcp.c directly?

This if-else is not needed. If is_integrity_protected, digest_length should always be 4.
Also define a macro for MAC-I len. It is being used at multiple places.
Similarly for IV length macro can be defined.

The above logic can go inside lib PDCP as well.
This is specific to PDCP and not user dependent.
You can reuse the pdcp_xfrm.hfn as well.
