[dpdk-dev] [PATCH] devtools/cocci: added script for ethdev namespace

[Aman Singh]

The cocci script is to help add prefix 'RTE_ETH' namespace to all enum
& macro of ethdev library in a backward compatible way. After the script
makes the changes few manual changes are required in rte_ethdev.h for
enum name changes.
