Hi all,
I 'm attempting to integrate DPDK code in an existing application, which in=
cludes <net/ethernet.h>.
That standard glibc header already provides a structure named ether_addr de=
fined 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 dire=
ctly always use <net/Ethernet.h> but I guess this is not done for some good=
reason)... isn't it?
Thanks,
Francesco Montorsi
