TSE (Triple Speed Ethernet) MAC on uClinux with MMU

As already pointed out by tones.rsa, the phy-id is optional. If not specified, the driver will autodetect. What is needed though is the correct mii-id. This one is specific to the board hardware you're using.

Currently you'll need to use a distinguished descriptor memory, otherwise the driver won't work. There once was the option to put the descriptor memory into system memory (DDR or whatever) but that went away when device tree support was merged. We'll need to update the altera_tse driver to be able to do this again.

Meanwhile I suggest you'd use a separate descriptor memory if possible.
