Hello,
I have few identical low end servers with the following integrated NICs:
02:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network
Connection
03:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network
Connection
On all servers is constantly increasing counters rx_errors, rx_length_errors
and rx_short_length_errors.
I tried the following settings 82574L:
* Increase Rx and Tx buffers from 256 to 4096 bytes
* Manual distribution of interrupts among the processors (IRQ Affinity)
* Disable Active State Power Management (ASPM) in the BIOS and Kernel
* Update kernel from 2.6.34 to 2.6.39
* Different e1000e drivers 1.0.2-k2, 1.3.10-k2, 1.6.3-NAPI, 1.9.5-NAPI
* Driver settings InterruptThrottleRate = 1,1
* Legacy Interrupt Mode IntMode = 1,1
* Disable LRO, GRO, GSO, Autonegotiate with ethtool
* Increase memory limits of the Linux networking stack
It seems that the number of errors does not depend on configuration or
driver version or the amount of traffic.
Then I tied to insert in one server additional NIC 82576 connected to the
same switch through the same patch cable and errors completely disappeared.
Does anyone have any idea why there are errors with 82574L NIC ?
