Indeed, the macb_configure_caps function is called a bit too late,
but ...

... I'm not happy with these changes.
I tried to keep  specific init steps of macb and at91_ether separated
and you're moving macb_configure_caps call (not required on at91_ether
HW) into macb_probe (the common probe part).

How about moving macb_configure_caps a bit earlier in the macb_init
function [1] ?

Best Regards,

Boris
