O.K, i will ask the dumb question....

Isn't fixed-link supposed to be used for links which are fixed?
Why would a fixed-link change?

The use cases i've seen for this is when you are connecting the MAC to
a Switch. The link is configured to its fastest mode and then left
alone.

Please could you give some more background information. What do you
have on the other end of this fixed link which keeps changing?
Obviously not a switch.

Thanks
Andrew
