Hi Todd,
Basically it's only with vlan that 10G interface is not working and we are
using the latest driver ixgbe-3.18.7.
In last mail the packet was actually sent without VLAN so there was no issue.
I have tested it more , and the problem reduced to this :
With VLAN the 10G driver is
I've tried some other tuning options (Increaasing the PCIe Max Read Size to
4096, for example) but I still haven't found a way to get westmere (X5670)
performance out of my Sandy/Ivy parts. It just seems wrong to me that where
the X5670 has no problem keeping up, the newer, better, faster E5-2670
Maksim,
The check_hang_subtask function is only meant to be run once every 2
seconds. As such you should only be seeing one interrupt per vector
every 2 seconds. How is this overloading your CPU? Are you seeing the
interrupts fire at a rate faster than 1 every 2 seconds?
The function is meant
Scott,
The fact that the rx_no_dma_resources counter is increment tells us this
is an issue with the CPU not being able to keep up. As such I don't
believe that modifying the PCIe settings such as the Max Read Size will
likely help to improve performance. The issue in such cases is usually
due to
The BIOS on my system (X9DRW-iF) does allow for me to disable the Ageing
Timer Rollover. I may try that on a less important system and report back.
I am aware of the locality of the PCIe on the new systems, and we have been
able to reduce the severity of the problem by limiting the number of RSS
The ixgbe driver strips vlan tags and this is by design as Todd mentioned this
due to 8021P support. There are different cases where the result may differ
based on the kernel version.
There is a long discussion regarding this issue here:
