Xilinx LLTEMAC driver issues

["Magnus Hjorth" <mh@omnisys.se>]

Hi,

I'm having some networking troubles with the Xilinx LLTEMAC driver from =
the
Xilinx Linux git tree (powerpc arch) on an ML403 board. EDK9.2SP2,
xps_ll_temac v1.00.b=20

The weird thing is, that it sort of half works. It successfully makes a =
DHCP
request and gets its IP address. I tried setting up a tftpd server, and =
I can
see UDP requests coming in but the response doesn't seem to come out. I =
also
tried running a TCP server on the board, and it can see and accept =
incoming
connections but after that no data seems to get through. I can ping out =
and
get around 40% packet loss.

Looking at /proc/interrupts, I can see both TxDma interrupts and RxDma
interrupts. No eth0 interrupts but that seems to be OK judging by the =
driver
source comments. Ifconfig shows no collistions, no dropped packets, no =
errors,
so the system seems to think that everything is OK.=20

Clues anyone? I'm starting to run out of ideas...

Best regards,
Magnus
