Re: Making Two ethernet interfaces up in Linux

Thanks for the reply.
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.

         We are trying to port Linux on Xilinx Board XUPV2Pro which is
similar in most aspects to the Xilinx ML300 board. Linux is up and
running for the original board i.e. having only one ethrnet interface.
Now since we wanted to have the board working as router, we designed a
daughter board with two ethernet phy interfaces. The MACs required for
that are instantiated in Xilinx ....

You have already the driver for the first MAC, then you should start from that
modifying the init procedure for example and all the others. Your driver
should initialize both the MACs and also create two devices calling
init_etherdev tow times. If you post your driver I can suggest what to
change. It is not so difficult.
