[LEDE-DEV] revisited: Nanostation m5 XW ethernet patch gone

[Felix Fietkau]

Hi Daniel,

The patch that you mentioned is not related to your issue at all, since
it only deals with the AT8032 PHY, which the NanoStation M does not
have. Maybe you can provide a more detailed description of what symptoms
you're seeing.

I did indeed clean up the AT8032 mess and solved it in the PHY driver
(controlled by platform data) instead of adding GPIO toggle hackery to
the Ethernet driver.
