Why?
Does the mac0 TX clock have an extra long clock line on the PCB?
Does the mac1 TX and RX clocks have extra long clock lines on the PCB?
Anything but rgmii-id is in most cases wrong, so you need a really
good explanation why you need to use something else. Something that
shows you understand what is going on, and why what you have is
correct.
