kernel: phy: add Aquantia PHY AQR111 & AQR111B0
|
||
|
|
|
||
|
|
Add the IDs for Aquantia PHY AQR111 and AQR111B0 as found in the GPL sources
|
||
|
|
of the Netgear RAX120v2 firmware v1.2.8.40.
|
||
|
|
|
||
|
|
This is a 5GbE chip but it reports support for 10G. Implement config_init()
|
||
|
|
to set max speed to 5G.
|
||
