Summary: Network driver for mpc8313erdb board does not work

All right, I give up. Which net device driver does a "mpc8313erdb board" use?

I'm seeing gianfar in the dmesg. Is it that?

I am working on mpc8313erdb board. I want to update current linux2.6.23 from freescale to latest version.there are 3 scenarios as below:
1: when I set up uboot as NFS boot, it hang on after IP-config:
