There are more things to fix.
First you must export rte_dmadev_trace_fp.h as it is included by rte_dmadev.h.
Note: you could have caught this if testing the example app for DMA.
Second, you must avoid structs and enum in this header file,
otherwise it cannot be included alone.
Look at what is done in other *_trace_fp.h files.
