Subject: [PATCH net-next v2 0/2] ethtool: add support for Fast Link Down as
 new PHY tunable

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.

v2:
- add describing comment in patch 1

Heiner Kallweit (2):
  ethtool: add PHY Fast Link Down support
  net: phy: marvell: add PHY tunable fast link down support for 88E1540
