On boards without EEPROMs, don't reset the chip on U-Boot's exit so that the MAC set by environment settings can be used by the OS later.
that isnt how the MAC is passed to the OS ... this change is incorrect
the OS must be able to get the MAC address regardless of the state of the network controller
Not if the MAC is stored in the volatile smc911x registers. Issuing a soft reset flushes these values - if U-Boot does that, the OS has no change getting them.
That's what I saw here and it is also stated in the datasheet.
