Hi,
I am getting link drops in my tegra based board with 82574l
NIC. The OS is Linux Ubuntu 13.04. The e1000e driver was upgraded to
3.04 to rule out any software problems. I am using iperf to reproduce
the problem.
The 2 platforms which runs iperf server and client are identical boards
with 82574l. I assign them static IP connected to each other using CAT5e
cable. From various forums, I read there are problems with ASPM with the
NIC. I have disabled ASPM in the kernel as well (just to be safe, even
if it already disabled in the driver). I have also tried disabling TSO.
But still can reproduce the problem.
Attached are the logs (TSO not disabled).
I couldn't find any error messages from the kernel nor the driver other
than the watchdog resetting the driver. Any pointers on how to fix the
link will be very much appreciated.
Thanks,
Tony
