No objection, but I wonder how we can resolve this case:
 https://nxr.netbsd.org/xref/src/sys/arch/hp300/stand/common/if_le.c?r=1.14#101

extern struct netif_stats	le_stats[];

static struct netif_dif le_ifs[] = {
/*	dif_unit	dif_nsel	dif_stats	dif_private	*/
{	0,		NLE0CONF,	&le_stats[0],	le0conf,	},
};
#define NLE_IFS (sizeof(le_ifs) / sizeof(le_ifs[0]))

struct netif_stats le_stats[NLE_IFS];
