Raspberry Pi 3b Plus USB-Ethernet lan78xx_eth address not set

[Sourabh Hegde Ramu]

Hello,

I have a Raspberry Pi 3B Plus which I want to integrate with U-boot
(v2023.10) .

I am using rpi_3_32b_defconfig to generate u-boot.bin. But while booting I
am getting below error

Loading Environment from FAT... Unable to read "uboot.env" from mmc0:1...
In:    serial,usbkbd
Out:   serial,vidconsole
Err:   serial,vidconsole
Net:   No ethernet found.

Error: lan78xx_eth address not set.

       scanning usb for storage devices... 0 Storage Device(s) found
Hit any key to stop autoboot:  0

In the "bdinfo", "current eth" is not set

current eth = unknown
eth-1addr   = (not set)
IP addr     = <NULL>

I also enabled LAN75xx in menuconfig and re-compiled u-boot. But still the
same error.

However on Raspberry Pi 3B, I don't see this error and "current eth" is set
to "smsc95xx_eth" and "ethaddr" is also available.

Can anyone please let me know the issue with Raspberry Pi 3b plus?

Thanks in advance.
