[dpdk-dev] [PATCH v5 1/1] test: new test structure for asymmetric crypto

[Shally Verma]

Hi Damian, Fiona, Arek

Though am bit late to come back to this. But I have question on mod_exp test vector.
Please see below.

There's already a testvector mod_p[] in file with leading 0. Where as I see this one duplicate of that but without leading 0.
Could you tell me if you ever tested with mod_p[] with leading 0 and if your qat PMD passed that?
