Subject: [PATCH 079/102] net-next: mediatek: add fixed-phy support
|
|
|
|
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.
