This adds support for Fast Link Down as new PHY tunable.
Fast Link Down reduces the time until a link down event is reported
for 1000BaseT. According to the standard it's 750ms what is too long
for several use cases.

This is the kernel-related series, the ethtool userspace extension
I'd submit once the kernel part has been applied.
