nit picking, but COMPILE_TEST is generally last on the line.

David will complain about reverse Christmas tree. You need to move
some of the assignments into the body of the function. This problems
happens a few times in the code.

You should look at the value of pause.autoneg.

It would be nice to avoid this forward declaration.

Is this documented?
