Hello!
I have C++ application compiles and works nice. But when I include
rte_hash_crc.h header everything goes away.

Hello!
Could anybody help me with this issue? :(
In this file widely used enum forward declarations which completely
incompatible with C++ and need some rewrite.

I fixed this issue with very dirty hacks.
I commented mentioned here lines in file
/usr/src/dpdk-2.0.0/x86_64-native-linuxapp-gcc/include/generic/rte_cpuflags.h:
//enum rte_cpu_flag_t;
//enum cpu_register_t;
// static const struct feature_entry cpu_feature_table[];
//static inline int
//rte_cpu_get_flag_enabled(enum rte_cpu_flag_t feature);
And everything compiled OK. But I thought C++ tests and compatibility
is should for dpdk.
