I don't believe I overlooked anything. I've come to this conclusion after
reading every response in this thread.

EEE support exists since the commit which I've mentioned on my patches
here. I am fixing it. I thought I had explained this clearly on the
patches.

Are you talking about the EEE_DIS bit on the trap? There's no default
setting there, it's up to the board vendor to enable/disable EEE by pulling
the affine pin low or high. So there's no intentional disabling by MediaTek
there. I see no need to ask the corporate regarding this.

This patch series does not in any way enable EEE on the switch PHYs and
MACs when it's disabled by default.
