[PATCH] net: mv88e6xxx: add missing SMI address init

[Lukasz Majewski]

Hi Marek,

> Driver does not currently initialize the smi_addr field, but instead
> keeps the default value. This leads to issues on systems with
> different hardware configuration. We can fix this problem by reading
> the SMI address from device tree.

I've posted some time ago patches for this driver:

https://patchwork.ozlabs.org/project/uboot/cover/20230601100005.2216345-1-lukma@denx.de/

Unfortunately, those were not pulled...

Maybe you would find fix for your issue, or prepare new version of it?


Best regards,
