Hi,
I have a Memec FG456 evaluation board with P160 module. I
am using Xilinx ethernet core (with default configuration
in mhs file) and the open source linux driver for Xilinx
EMAC. It seems that the ethernet device is detected
correctly but I cannot seem to ping any machine in my
network. I can ping myself though. Here are some diagnostic
results.

From the diagnostic results cited above it looks like the
problem is in your host: the tagret sends 7 ARP requests
which are decoded correctly (I assume this because neither
you nor you host complain about ARP requests contents), but
host doesn't respond to them.
I would check the ARP requests contents and then your host settings.
Best regards,
Andrei

Hi Andrei,
After my original message, I set up system arp cache
manually for both host and target so they dont need to send
any arp requests. Using tcpdump on the host I sniffed the
ping requests and the host seems to respond to the ping
requests from target but target never receives them.
Here are my results (192.168.0.55 is the target and
192.168.0.5 the host)
Ontarget
--------
arp -s 192.168.0.135 00:0D:56:C5:8E:E2
ping 192.168.0.135
On host
-------
[root@ws054 tmp]# tcpdump icmp
tcpdump: listening on eth0

So it seems that TX for EMAC is working fine but there are
issues with the RX side. I would like to add that I am not
using the patch that you sent few days back.
