So far, nobody has corrected me that the MAC is not connected to an
SFP socket. So i see two sorts of abuse going on here:

1) Using a fixed link with a hack to allow 10G. phylink allows 10G
   fixed links without an hacks.

2) Using a fixed link when not even appropriate since phylink should
   be used to control the SFP.

Now, you can do whatever you want in your Vendor Crap tree. But there
is no reason mainline should help you support your vendor crap tree.

To make progress here, you need to add an in tree user of this generic
change. And since that means an ACPI user, you need to follow what has
been set out in the other thread. You need an ACPI maintainer to ACK
it. And to get an ACPI maintainer to ACK it, you need a specification,
and proof it is being used. And to get my ACK, it needs to be valid
use of it as well.
