Subject: [PATCH] drivers: net: phy: aquantia: enable AQR112 and AQR412
|
|
|
|
Adds support for AQR112 and AQR412 which is mostly based on existing code
|
|
with the addition of code configuring the protocol on system side.
|
|
This allows changing the system side protocol without having to deploy a
|
|
different firmware on the PHY.
