Realtek 8169 based device

Hi,

Firstly, apologies if this is the wrong place to ask this. Please let
me know if somewhere else is more appropriate.

Secondly, I realise that the kernel I'm using here is quite old.
However, this is the kernel provided by the version of Openfiler I'm
using, so updating isn't a simple matter.

I've just installed a Zyxel GN680T NIC into a PC (purchased here:
http://www.dabs.com/products/zyxel-gn680t-gigabit-pci-network-card-75Q5.html).
Initially it wasn't recognised by the device.

03:01.0 0200: 106c:8169 (rev 10)

I had a look at the driver source, and it didn't appear to be
correctly recognising the PCI IDs. I managed to recompile the module,
adding in support for this device as follows:


        { PCI_DEVICE(0x106c,    0x8169), 0, 0, RTL_CFG_0 },

When I load this new module, the device is correctly recognised, and
ethtool can give sensible information and report negotiated link
speeds etc. However the network card fails to work (I'm pretty sure it
was reporting transmit time outs).

Can anyone offer any advice on getting this card to work?

Thanks

Which kernel version is it and does an "XID" line appear for the r8169
driver in the kernel log ?

In the end there may be only two paths left : upgrade the kernel or
backport the driver.

It could help if some openfiler developer was available, at the very
least to retrieve an adequate kernel build tree if backporting is the
only option.

Sorry, I realised after hitting send that I hadn't posted the kernel version:

[root@nas ~]# uname -a
Linux nas.gently.org.uk 2.6.29.6-0.30.smp.gcc3.4.x86.i686 #1 SMP Thu
Nov 4 19:54:00 GMT 2010 i686 i686 i386 GNU/Linux

The 8169 driver line is:

[    5.216930] eth1: RTL8169sb/8110sb at 0xf8034000,
4c:00:4e:00:08:fe, XID 10000000 IRQ 16

Ondrej Zary replied to me suggesting I reseat the card as there is
only one bit difference between the Hynic ID (0x106c) and Realtek ID
(0x10ec). I'm at work and the machine is at home, so I can't check
that until later today.

backport the driver.

I have already recompiled the driver to add in the handler for this
ID. If it turns out that this is in fact a correct ID, then at least I
know I can successfully compile and run any code should that become
necessary.

Thanks for the input.
