Subject: [PATCH] net: phy: realtek: rate-adapter in C22 mode
|
|
|
|
Use rate-adapter mode in case the PHY is connected to the host using
|
|
Clause-22 MDIO.
|
|
|
|
This is necessary because phylink only handles dynamically switching the
|
|
interface mode if the PHY is connected using Clause-45 MDIO.
