Are these config options used?

Is this defined anywhere?

Instead should RTE_LOG_DP used?
And since other macros uses dynamic log functions, why here use static method,
what do you think using new method for data path logs as well?

used with its new meaning.

This is wrong, nb_segs is 16bits now, this check has been updated in i40e
already.
