So there is no need to do an “sudo apt-get install ethtool” to install the “ethtool” module to the My Cloud OS. Enable dumping of the library state when receiving a signal. This feature is only enabled by default in the debug library. It may be disabled all the time by setting the variable to 0. Setting the variable to a positive number else will enable the dumping even if the non-debug library. If bigger than 1, the dumping will be more detailed. creighton secondary reddit Oct 04, 2019 · This means that your driver has not implemented the ethtool get_channels operation.

Inspired by their work I had like to extend it a step further and discuss introducing open-vswitch based flows for multiqueue aware virtio-net queuing. Deciding Whether to Enable the Multi-Queue. This section helps you decide if you can benefit from the Multi-Queue. We recommend that you do these steps before you configure the Multi-Queue: Make sure that network interfaces support Multi-Queue. Make sure that SecureXL is enabled. Examine the CPU roles allocation. Examine the CPU cores utilization. ID: 14008: Package Name: kernel: Version: 4.18.0: Release: 193.28.1.el8_2: Epoch: Summary: The Linux kernel, based on version 4.18.0, heavily modified with backports [6]) equip two or more hardware Tx queues to enable transmission parallelization or MAC-level QoS. These hardware features cannot be supported easily with the current network subsystem. This paper describes the design and implementation for the network multiqueue patches submitted to net-dev [2] and LKML [1] mailing lists early this year, 10) Fix and enable offload features by default in 8139cp driver, from David Woodhouse. 11) Support both ipv4 and ipv6 sockets in a single vxlan device, from Jiri Benc. 12) Fix CWND limiting of thin streams in TCP, from Bendik Rønning Opstad.

NAME. ethtool - query or control network driver and hardware settings. autoneg on|off. Specifies whether pause autonegotiation should be enabled.The NIC drivers on Linux typically contain statistics that show the total number of packets and bytes transmitted and received. These can be accessed using the ethtool command, e.g. ethtool -S enp5s0f1. The drivers actually maintain a very large number of statistics, so to get at just the queue statistics you might use something like this: A multiqueue network card, which offers enough Combined RX/TX channels, with native XDP support is highly recommended. Successfully tested cards: Intel series 700 (driver i40e), maximum number of channels per interface is 64. Intel series 500 (driver ixgbe), maximum number of channels per interface is 64.

Where number of queues is equal to the number of virtual processors assigned to the virtual machine.
