I'm not sure that is a valid name for a Signed-off-by. I would expect
something like:

This phy-mode is wrong. There is a long discussion about this, started
from a BMC submitted by IBM. Please wait until Aspeed fix the MAC
driver before adding support for RGMII based ethernet. You are
probably innocent here, apart from failing to sanity check vendor
advise, which happens to be wrong.

The max-speed parameter should also be unneeded. Unless you have a
real need for it. Does this MAC/PHY combination support higher speeds,
but they are broken for some reason, so you need to avoid them?
