[PATCH V4 3/4] net-next: mediatek: add fixed-phy support

From: John Crispin <hidden>
Date: 2016-06-03 08:18:11
Also in: linux-mediatek, lkml
Subsystem: mediatek ethernet driver, networking drivers, the rest · Maintainers: Felix Fietkau, Lorenzo Bianconi, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

The MT7623 SoC has a builtin gigabit switch. If we want to use it, GMAC1
needs to be configured using a fixed link speed and flow control settings.
The easiest way to do this is to used the fixed-phy driver, allowing us to
reuse the existing mdio polling code to setup the MAC.
