2ghz should be disabled on this router.
And I think 'mediatek,mtd-eeprom' should be defined as<&factory 32768> instead of <&factory 0x8000> according to WHR-1166D.dts
Actually I didn't have this router.But I think this is the reason that the MT7612E radio always gets a random MAC address on this router.

BTW,Roger,could you please test if this patch can fix the MAC address problem you told in your mail?

It doesn't have 2ghz wireless interface, or it is that we are not capable of 
supporting it at moment?

This is a router with mt7620a soc for 2.4GHz wireless and mt7612e for
5.8GHz wireless.

Ah.Sorry,I mean 2.4GHz support for MT7612E should be disabled.

You're right. This should be patched.

Both definitions are the same, since 0x8000 hex == 32768 dec.

I tried both, with equal results.

try 0x8004 as 0x8000 holds the chip id and right after that is where the
mac is located

Hi,

I tried with 0x8004 and I also got a random IP address. Actually, I changed
this block in in eeprom.c (line 571) [1]:

if (!is_valid_ether_addr(dev->macaddr)) {
    eth_random_addr(dev->macaddr);
    dev_printk(KERN_INFO, dev->dev,
        "Invalid MAC address, using random address %pM\n",
    dev->macaddr);
}

to:

if (!is_valid_ether_addr(dev->macaddr)) {
    dev_printk(KERN_INFO, dev->dev,
        "Invalid MAC address %pM\n",
        dev->macaddr);
    eth_random_addr(dev->macaddr);
    dev_printk(KERN_INFO, dev->dev,
        "Using random address %pM\n",
        dev->macaddr);
}

and I see this message:

can you do a "hexdump -C /dev/mtd2" and paste the output please ?

Yes, the MAC is where expected. I've tried unloading and reloading the
mt76pci module; the second line of the log passed unnoticed for me before.

Does "no of_node" have something to do with the issue?

Actually, you only need to run "make target/linux/clean" :D

Hi,

I added some prints to the eeprom.c file and saw that in function:

static int mt76_get_of_eeprom(struct mt76_dev *dev, int len)
{
    int ret = -ENOENT;
#ifdef CONFIG_OF
    struct device_node *np = dev->dev->of_node;
    struct mtd_info *mtd;
    const __be32 *list;
    const char *part;
    phandle phandle;
    int offset = 0;
    int size;
    size_t retlen;

    dev_printk(KERN_INFO, dev->dev, "mt76_get_of_eeprom. Step 0 (before
!np)");

    if (!np)
        return -ENOENT;

    dev_printk(KERN_INFO, dev->dev, "mt76_get_of_eeprom. Step 0 (after
!np)");
[...]

if does not go further than (   if (!np)   ).

Any ideas?

Sorry I forget another thing.....
It should be :
  pcie-bridge {
        mt76@0,0 {

instead of:
     pcie0 {
        mt76@0,0 {

I'll send another patch later....................
