Dear maintainer,
Im developing device which is based on ARM processor and the processor
supports PCI Express root-port.
Im trying to install Intel X520-SR2 adapter on this device(Linux) but there
is problem when ixgbe driver probe device.
Here is brief system configuration.
Processor :
This time, I tried "Intel(R) Gigabit ET Dual port server adapter" with igb
driver.
But this adapter also has problem reading some kind of NVM.
I'm not sure the errors have any relation to previous X520 adapter errors.
[6.17] libphy: Fixed MDIO Bus: probed
[6.18] igb: Intel(R) Gigab

Hi Minho,
It sounds like your NVM isn't correctly set up. I'm just the ixgbe driver
owner so don't configure eeprom's myself, but I'll see what I can find out or
find someone to point you at. When you purchased the x520 LOM (I'm assuming
your developing a LOM system) weren't you provide a dev
Hi Don,
Thanks for all the explanations. It will be a great help.
Can you suggest some pointers to look more into PCIe bus
configurations/tuning ?
Rgds,
Nishit Shah.

Greetings Robert!!! Good to hear from you although I'm sorry to hear that
you're seeing an issue with the 82576.
I'm forwarding this email to the Sourceforge e1000_devel list where perhaps
someone may have heard of the issue you describe.

Hey Minho,
It has also been mentioned that this may be an issue with your PCIe connection.
So could you also provide the output from 'lspci -vvv'.
Thanks,

Hey Nishit,
I'm not sure what I can tell you. It looks like your device is loaded down
with small packets we know this will overload the PCI bus, this will of course
adversely event latency. You could try something like DCB. Put your traffic
that needs low latency on one TC and the small pac

Hey Nishit,
Another engineer reminded me that IOMMU is never good for latency. You should
also make sure that is disabled.

Thank you for your kind reply.
I attached 'lspci -vvv' result. But 'ethtool -i eth0' was failed with
message like below,
"Cannot get driver information: No such device"
I guess net_device not registered by the errors.
JFYI, I'm using off-the-shelf adapter not LOM.
Thanks and Regards,

Thought I would add some more details, the issue is with the 82576 rev
1, on a dell C series system.
current setup is a 2 port bond using lacp. There are 2 tagged vlans
(802.1q) running on top of this.
The issue is traffic flows for 5-10 minutes, then drops all connections.
