Subject: [PATCH 080/102] net-next: mediatek: properly handle RGMII modes
|
|
|
|
If an external Gigabit PHY is connected to either of the MACs we need to
|
|
be able to tell the PHY to use a delay. Not doing so will result in heavy
|
|
packet loss and/or data corruption when using PHYs such as the IC+ IP1001.
|
|
We tell the PHY which MII delay mode to use via the devictree.
|
|
|
|
The ethernet driver needs to be adapted to handle all 3 rgmii-*id modes
|
|
in the same way as normal rgmii when setting up the MAC.
