// XXX: This is a workaround for a bug in the Tizen SDK header files. It is not
//      possible to include both <net/if.h> and <linux/if.h> at the same time.
//      This will cause warning that struct ifmap is redefined. On Linux, this
//      is not a problem, because in <linux/if.h> the struct is guarded with
//      ifdef. To prevent this, we will define _LINUX_IF_H, so the <linux/if.h>
//      will not be included.
