Tracking upstream.
Comment 2 Jakub Jelinek 2013-04-02 09:57:18 UTC 
BTW, the source is clearly broken, so you'd better fix this:
unsigned char __suggest_mac[6] = {0xEA, 0x1A, 0xDE, 0xAD, 0xBE, 0x00};
unsigned char *suggest_mac(void)
{
 int i;

 for (i = 6 - 1; i >= 0; i++) {
  if (++__suggest_mac[i] != 0)
   break;
  ++__suggest_mac[i];
 }
 return __suggest_mac;
}

I bet i++ was meant to be i-- instead.
