Fast Ethernet device driver for MPC885

Fast Ethernet device driver for MPC885

[scarayol]

Hi all.

I use a custom board with a MPC885 microprocessor. I want to test the
Ethernet chain on my board so i made an external loopback on the Ethernet
port. I want to transmit datas and read the received datas.

Which driver have i to use and which name to open it. I don' see any driver
that seems to be the fec one in /dev/..  I think i have to use the routines
in pqfec.c instead of fec.c. But I don't know how the driver works.
Which kind of driver is it and how access to the routines from user space
in order to do my tests ?

Thank you really for your help.

Well, fec registers as a network device, so you should use the sockets AP=

access it.

Don't know about them, sorry.

Read above. "man socket" is a good start.
