Shantanu, Can you post the xemac_g.c file in the xilinx_enet directory? Also, which version of the EDK are you using? There was a bug in EDK 7.x that prevented multiple Ethernet interfaces from working properly.
It would also be helpful to see xparameters_ml300.h from the arch/ppc/platforms/xilinx_ocp directory.

The driver which we are using for the ethernet is provided by Xilinx. In the Linux kernel source, it is located in net/xilinx_enet directory. We are attaching the adapter file for the driver provided by Xilinx for the ethernet. When we gave a first try, it showed two ethernet interfaces eth0 and eth1 as an output of ifconfig command but only eth0 works, when eth1 is disabled. When both interfaces are up, neither interface works. While even when eth0 is disabled, eth1 interface doesn't work. With regards, Shantanu.
