conflict between ether_addr defined in rte_ether.h and the same structure in <net/ethernet.h>

Hi all,

I 'm attempting to integrate DPDK code in an existing application, which includes <net/ethernet.h>.
That standard glibc header already provides a structure named ether_addr defined as:

struct ether_addr
{
  u_int8_t ether_addr_octet[ETH_ALEN];
} __attribute__ ((__packed__));

So the result is that gcc complains about the redefinition:

My idea here is that DPDK should rather define an "rte_ether_addr" (or directly always use <net/Ethernet.h> but I guess this is not done for some good reason)... isn't it?

Thanks,
