If you have a machine with a BMC enabled but cannot receive IPMI traffic after loading or enabling the driver, try disabling this feature. I’ll update this thread if the issue recurs. By Bruce W Allan, one of the authors of the driver. Sign up using Facebook. August 15th, 3.

It is useful only if TxIntDelay is non-zero. By Bruce W Allan, one of the authors of the driver. So if the core changes all drivers must be netwrk with it. Results 1 to 10 of We don’t supply patches against the kernel source to allow for static linking of the drivers.
If I restart the network connection, it’s fine again.
The install location listed above is the default location. August 16th, 8. Interrupt Throttle Rate controls the number of interrupts each interrupt vector can generate per second.
Increasing ITR lowers latency at the cost of increased CPU utilization, though it may help throughput in some circumstances. It will be updated and maintained automatically.

negwork Setting InterruptThrottleRate to a value greater or equal to will program the adapter to send at most that many interrupts per second, even if more packets have come in. Let me know if you need more clarification.
The driver copies all packets below or equaling this size to a fresh receive buffer before handing it up the stack.
This should only be needed when attempting to link with an older switch that does not support auto-negotiation or one that has been forced to a specific speed or duplex mode.
Kernel is the core of any operating system. That also seemed to disable my ethernet connection, when I run ifup eth0, it reports that the device can’t be found. You can use the insmod command for 2. The two other lines, I don’t understand either what they are doing. If the traffic is mostly transmit or mostly receive, the interrupt rate could be as high as Sign up or log in Sign up using Google. What exactly does this clarify to us in this context?
Alternatively, you can use ethtool version 1.
August 15th, 4. Linux Driver Install I have bigabit few question though, What are these doing: However, this is generally not suitable for bulk throughput traffic due to the increased CPU utilization of the higher interrupt rate. Current configuration, please let me know if any other diagnostic info would be helpful. IntMode allows load time control over the type of interrupt registered for by the driver. Dynamic mode This mode attempts to 82577ln interrupts per vector while maintaining very low latency.

The ee project can be found on sourceforge here. The default behaviour of the driver previously assumed a static InterruptThrottleRate value ofproviding a good fallback value for all traffic types, but lacking in small packet performance and latency.
August 16th, negwork. In this case, there are two network ports supported by ee in the system. The install location listed above is the default.

Increasing this value adds extra latency to frame reception and can end up decreasing the throughput of TCP traffic. I need to tell someone my MAC address imminently so I can be added connectikn their router, but I am not at my computer.
Basically, I’m seeing the behavior described here:
