Subject: [PATCH 16/70] NET: MIPS: lantiq: non existing phy was not handled
|
|
gracefully
|
|
|
|
The code blindly assumed that that a PHY device was present causing a BadVA.
|
|
In addition the driver should not fail to load incase no PHY was found.
|
|
Instead we print the following line and continue with no attached PHY.
|
|
|
|
etop: mdio probe failed
|
