对于AR9531的MAC地址，应该保存在ART区中。

查看分区，分区情况如下:

root@OpenWrt:/# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00040000 00010000 "u-boot"
mtd1: 00010000 00010000 "u-boot-env"
mtd2: 00e30000 00010000 "rootfs"
mtd3: 00c40000 00010000 "rootfs_data"
mtd4: 00150000 00010000 "kernel"
mtd5: 00010000 00010000 "factory"
mtd6: 00010000 00010000 "art"
mtd7: 00f80000 00010000 "firmware"
root@OpenWrt:/#

将ART分区导出，查找mac地址位置：

root@OpenWrt:/dev# dd if=/dev/mtd6 of=/tmp/222
128+0 records in
128+0 records out
root@OpenWrt:/dev#

用WinSCP将 /tmp/222 文件拷贝到PC端，用 Winhex 打开文件查看，

跟设备端用 ifconfig查看到的相同。
