Just for my understanding, by "bootloader takes care of proper mac
delays for now" you mean you have a 'hacked' bootloader which no
longer adds delays, unlike the stock aspeed bootloader which does add
delays? Because otherwise, i don't see how rgmii-id will work.

RGMII cannot do more than 1G, so max-speed is pointless.
