   4 Subject: [PATCH 81/91] net-next: mediatek: add fixed-phy support
   5
   6 The MT7623 SoC has a builtin gigabit switch. If we want to use it, GMAC1
   7 needs to be configured using a fixed link speed and flow control settings.
   8 The easiest way to do this is to used the fixed-phy driver, allowing us to
   9 reuse the existing mdio polling code to setup the MAC.
