Subject: [PATCH 71/82] net: sparx5: skip low-speed configuration when port is
|
|
RGMII
|
|
|
|
When doing a port config, we configure low-speed port devices, among
|
|
other things. We have a check to ensure, that the device is indeed a
|
|
low-speed device, an not a high-speed device. Add an additional check,
|
|
to ensure that the device is not an RGMII device.
