Return values not checked. Return type of nitrox_sym_pmd_destroy is not void.

Why do you need a wrapper over RTE_CRYPTODEV_NAME_MAX_LEN

Logs can be squashed in your first patch.
Let this patch be specifically to initialize/create the Nitrox symmetric cryptodev

In your previous patch, I could see that crypto_nitrox was used without the macro while doing malloc.

Do you support all these features in this patchset?
I believe these should be added where they are supported along with the features.ini changes.
