[dpdk-dev] [PATCH 2/4] ethdev: move RTE_ETH_FPTR_OR_ERR macros to header

Bruce Richardson bruce.richardson at intel.com
Fri Jun 12 13:28:14 CEST 2015


Move the RTE_ETH_FPTR_OR_ERR, and RTE_PMD_DEBUG_TRACE macros to the 
header file, so that they can be used in the static inline functions
there. In doxygen comments, mark them as for internal use only.
