AES CBC is not an auth algo
You should use AES CBC MAC
Please use the same notation as there in default.ini
Check for all the names.

Increment should be 1 for all HMAC cases.

Do you only support key sizes of 1 and 16? I see increment =0 in many cases.

Why are these enums needed, Aren't these replica of rte_sym_crypto.h
Are these enum values getting filled in some HW desc/registers. If so, then
Probably move it to the hw folder.
