Description
The cpmac driver can't detect the ADM6996L switch and fails with "No PHY present".
I have a temporary patch that forces the driver to use the ADM6996L.
Please allow instead the driver to detect the switch.

Replying to florian:
Duplicate of #99
Ticket #99 is for the Marvell 88E6060 switch used in the DG834Gv2.
I get the following on my DG834Gv2 currently running build 7039. Should #99 maybe be closed instead?

The Infineon ADM6996LC switch can't be detected too.
Also, I can't get it working even with the attached patch or by setting dumb_switch = 1

Could you post a dmesg log of the current trunk for your device?

This patch is unacceptable as it breaks other devices
