Beschreibung
The Mellanox WinOF-2 Rev 1.80.51000 for Windows package contains the following components:
– Ethernet driver
– IPoIB driver
– Basic tools
– Performance tools
– Documentation
Big Fixes:
– Removed from the Windows INF file all the device IDs that are not in use.
– Fixed a false alarm that indicated that a send queue was stuck and as a result a miniport reset was performed.
– Fixed a rare case that caused a BSOD when switched from a single RQ to RSS.
– Fixed certification issues that occurred when running ConnectX-4 Lx at 25Gb/s link speed.
– Fixed an issue that caused the firmware to get stuck during VM migration in SR-IOV mode or upon PF driver restart.
Known Issues:
– In some scenarios, the device reports one schedule queue more than the supported number of schedule queue.
– In some scenarios, since the default LRO/RSC coalescing value is 4K, 100GbE bandwidth cannot be reached. Workaround: Increase the LRO/RSC registry key defaults to higher than 4K.
– Setting the TransmitBuffers parameter to a value that is not a power of 2 causes a BSOD while sending packets. Workaround: Set the TransmitBuffers parameter to values which are a power of 2
– When the VMQ mode is enabled in a virtual switch, the RSS-enabled network adapter supports only 60 VMNICs, in spite of the 124 advertised. Thus, only 60 VMQs for virtual NICs are available and HLK VMQ tests fail. Workaround: To pass HLK VMQ tests, disable virtual switch RSS, using the following powershell command: Set-NetAdapterAdvancedProperty -name <Device name> -RegistryKeyword „RssOnHostVPorts“ -RegistryValue 0
– Running RDMA from the host when SR-IOV is enabled is not fully supported.
– The „NDISTest 6.5 – [2 Machine] – Stats“ HLK test may fail due to inaccurate statistics caused by the counters caching mechanism in the driver. Workaround: Disable the counter caching mechanism, using the following PowerShell command: New-NetAdapterAdvancedProperty -name <Adapter name> -RegistryKeyword „UpdateStatsCacheOnDemand“ -RegistryDataType REG_SZ -RegistryValue 1
– Updating the non-default vPort’s VM network interface RSS parameter during heavy traffic in vRSS mode could cause the host and non-default vPorts network interfaces to reset, and a momentary disruption in network connectivity.
