Three-Speed Ethernet support on MPC8560 (TSEC)

Three-Speed Ethernet support on MPC8560 (TSEC)

[Nathael PAJANI]

Hi all!

I'm working on a port of linux (2.6.13-2) on an Actis-computer board, 
based on the Freescale MPC8560 Processor.

I solved the problems I had with the init process, and I actually have 
the console (SCC1) and one ethernet controler (FCC3) running.

I will now go on with the Three-Speed Ethernet Controler, and there 
actually seem to be no support for it, but maybe I did not look at the 
right place?

I got another question, about the FCC driver: it uses a "big" structure 
"fcc_enet_t" wich seems to be aimed at stats. This is initialised, but I 
did not find where this is used. Is it?

Thanks.

The TSEC has been supported for a long time.  The driver is call  
gianfar (drivers/net/gianfar*).

The FCC enet driver has been completely rewritten recently and is in  
the process of being accepted into the kernel.  Hopefully one of the  
guys with more knowledge on the details will be able to help you on  
the specifics.

OK, I found it, and remembered that at the begining of the port I 
wondered what the "struct platform_device ppc_sys_platform_devices[]" 
was for, now I know. and I'll try this for the FCC3 too.

There is a problem though, which I already had (and fixed) with the 
boot-loader: The gigabit ethernet is not set up correctly: Everything is 
fine with a Gigabit switch, but with a Fast ethernet switch there is no 
communication.
I'll look for this on monday!

Thanks a lot for the help !

fcc_enet_t is in the CPM parameter area. It is used but the statistics
it provides are not, since we properly update the linux net device stats
manually.
