Greetings,
I would like to report a bug to you. The same problem was reported to
OpenWRT developers. But, they suggest me report it to linux wireless.
Problem:
The wireless card can not be recognized. But, an iface with wrong MAC
is created.
wlan1 Link encap:Ethernet HWaddr 00:06:4E:E8:00:00 <== Wrong MAC, the
correct MAC is E8:4E:06:00:74:61. Looks like byte-swapped.
UP BROADCAST MULTICAST MTU:1500 Metric:1 <=== Not running
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
After making changes according to
https://forum.openwrt.org/viewtopic.php?id=30132,
the card can now be recognized with correct MAC and can be operated.
But, it does not work yet.
No RX in AP mode. No TX & RX in STA mode. I guess the TX in AP mode is
meaningless.
Wifi Card: Unknown brand, RT3070 chipset, USB
Platform: Openwrt (MIPS, BCM6358, big-endian)
Kernel:

Obviously, that driver fails to work on a big-endian platform. For tracking
purposes, please open a bug report at bugzilla.kernel.org. That will also be a
location for exchanging trial patches.
I have an RT3090 USB device and a MacBook G4 that uses the PPC processor, thus I
have a test bed for investigating this problem.

I do see a problem. Looking at one piece of your patch, we see
- rt2800_register_read_lock(rt2x00dev, EFUSE_DATA3,
- (u32 *)&rt2x00dev->eeprom[i]);
+ rt2800_register_read_lock(rt2x00dev, EFUSE_DATA3, ®);
+ *(u32 *)&rt2x00dev->eeprom[i] = le32_to_cpu(reg);
The last statement of rt2800_register_read_lock() does an le32_to_cpu()
conversion of the output value (3rd argument), but rt2x00dev->eeprom is le16,
which is why a double conversion le32 => be32 => le32 is needed. Your second
line should be
*(u32 *)&rt2x00dev->eeprom[i] = cpu_to_le32(reg);
That does the same thing, but makes it clearer what is happening.
I am having to rebuild the Ubuntu system on my Mac, which will take a while.
When that is done, I will be able to test.
