Web3 jul. 2024 · As per code it looks symmetric, but wanted to know if ENA hardware has such capabilities and can be exposed until our primary requirement of customizing the RSS hash key and indirection table is available. Let us know. Today the driver doesn't support it. With a slight driver modification you can achieve that. WebThe RSS hash key and indirection table may be changed by the ethtool -X command. The RSS hashing feature (hardware offload) can be enabled/disabled via ethtool -K. Example – Enabling/disabling RSS: # ethtool -K eno0 rxhash on Checking RSS status: # ethtool -k eno2 grep hashing receive-hashing: on

WebObserving RSS on ixgbe: Advanced RSS Configuration - RSS Hash Indirection Table. This case study leverages commands which may be unsafe in your environment (i.e. commands which change interface configuration, send packets with spoofed source address, etc.). Web14 dec. 2024 · The overlying driver chooses a hashing function, type, and indirection table. To set these configuration options, the driver sends an OID set request of OID_GEN_RECEIVE_SCALE_PARAMETERS to the miniport driver. Overlying drivers can also query this OID to obtain the current RSS settings.

When reviewing the Indirection Table, if the second number is all the same, it is a problem and would mean that one processor is more heavily favored over the others and might be indicative of a driver issue. 2.

Web1 mrt. 2024 · The indirection table contains entries of RX queue indices into which the corresponding packet will be inserted. Finally, the processing cores poll the queues, fetch packets and process them. Toeplitz Hash Algorithm In the default RSS algorithm the NIC computes the hash value based on the packet header entries using the Toeplitz hash … Web14 dec. 2024 · The RSS hashing type specifies the portion of received network data that a NIC must use to calculate an RSS hash value. Overlying drivers set the hash type, function, and indirection table. The hash type that the overlying driver sets can be a subset of the type that the miniport driver can support. For more information, see RSS ...
WebReceive-Side Scaling (RSS), also known as multi-queue receive, distributes network receive processing across several hardware-based receive queues, allowing inbound network traffic to be processed by multiple CPUs.
Web4 sep. 2015 · Quick methodology to check RSS under Windows 8.1 with three easy commands: - Launch PowerShell as Administrator - "get-NetAdapterRSS" - If RSS is enabled in the NIC's driver there is going to be a line with "Enabled" and "True" however the property "IndirectionTable" must not be empty (this it is on all NICs where RSS is not … top anonymous search engineWeb1 sep. 2014 · RSS is a scalability technology that distributes the receive network traffic among multiple processors by hashing the header of the incoming packet and using an indirection table. A NIC uses a hashing function to compute a hash value over a defined area (hash type) within the received network data. The defined area can be noncontiguous. top antenneWeb26 mei 2024 · The lowest number CPU to use for RSS. Because this value is incorporated into the indirection table, set BaseCpuNumber to zero.
