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

From: John Crispin
Date: Fri Jun 03 2016 - 04:18:39 EST


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.
