The result of not disabling LRO when combined with ip forwarding or bridging can be low throughput or even a kernel panic. These drivers are only supported as a loadable module at this time. Intel is not supplying patches against the kernel source to allow for static linking of the driver.

For questions related to hardware requirements, refer to the documentation supplied with your Intel adapter. All hardware requirements listed apply to use with Linux. Alternatively, you can use ethtool version 1. Instructions on updating ethtool can be found in the section Additional Configurations later in this document.

Select the link for your adapter. Results may vary if you mix speed settings. Not all modules are applicable to all devices.

The link speed must be configured to either 10 Gbps or 1 Gbps to match the link partners speed capabilities. Incorrect speed configurations will result in failure to link. If you plug in a different type of module, the driver will not load.

Other module types are not supported. Please see your system documentation for details. Active direct attach cables are not supported.

If you have just recompiled the kernel reboot the system before building. Move the base driver tar file to the directory of your choice.The wider register gives space to hold multiple packet buffers so as to save instruction number when processing bulk of packets.

Some constraints apply as pre-conditions for specific optimizations on bulk packet transfers. Scattered packets are not supported in this mode. The following devargs options can be enabled at runtime. They must be passed as part of EAL arguments. For example. We call this behavior as fully checking. As vPMD is focused on high throughput, it assumes that the RX burst size is equal to or greater than 32 per burst. In DPDK release v When running l3fwd with vPMD, there is one thing to note.

If this feature is enabled, the VF must use the advanced context descriptor correctly and set the CC Check Context bit. Because kernel PF thinks the VF is malicious. DPDK should check if the advanced context descriptor should be set and set it.

And DPDK has to ask the info about the header length from the upper layer, because parsing the packet itself is not acceptable. Some kernel drivers already disable MDD by default while some kernels can use the command insmod ixgbe. For example, if there are 6 ixgbe ports, the command should be changed to insmod ixgbe.

The statistics of ixgbe hardware must be polled regularly in order for it to remain consistent. The maximum time between statistics polls that ensures consistent results can be calculated as follows:.

This behavior is based on the kernel driver behavior. Because the errata of X states that the Interrupt Status bit is not implemented.

Talend tmap filter example

The errata is the item 22 from X spec update. Since the bit is not implemented in X, the irq cannot be handled correctly and cannot report the event fd to DPDK apps. Then apps cannot get interrupts and dmesg will show messages like irq No. Each port representor corresponds to a single virtual function of that device. Currently hot-plugging of representor ports is not supported so all required representors must be specified on the creation of the PF.

We can see from your dmesg output that it is failing to communicate correctly with the PCIe card in the failing server, but works correctly in a different server.

You can try using a different PCIe slot, if you have another one available, checking that your NIC and riser card if any are firmly seated, or replacing the riser card or motherboard.

It could also be, if you haven't actually tried this specific NIC in a different server and had it work, that the NIC itself is bad. After I ran the BootUtil to update the firmware, these cards work like a charm. Sign up to join this community. The best answers are voted up and rise to the top.
