While running the IPsec unit test program the following
segmentation fault is occurring:

This is crypto-dev enqueue data-path, if I am not mistaken.
I think in that case it is caller responsibility to make sure that ops[] contain valid crypto-ops
(as in majority of other data-path functions).
Suppose the main question here - why ipsec UT passes NULL as crypto-op here?

[Fiona] Agree with Konstantin - it's the data-path - we expect a valid op ptr.
Can the real issue be related to the recent addition of asymmetric QAT PMD?
Not all QAT PMDs support symmetric crypto now.
Is IPSec unit test finding a QAT asymm PMD and not checking it's capabilities 
or checking but not handling the result well and following a path that passes a NULL op to it?
