For the complete list of Ethernet and InfiniBand Known Issues and Limitations, see
MLNX_VPI_WinOF_Release_Notes.pdf.
3.1 Hyper-V with VMQ
Mellanox WinOF Rev 4.60 includes a Virtual Machine Queue (VMQ) interface to support
Microsoft Hyper-V network performance improvements and security enhancement.
VMQ interface supports:
• Classification of received packets by using the destination MAC address to route the
packets to different receive queues
• NIC ability to use DMA to transfer packets directly to a Hyper-V child-partition's
shared memory
• Scaling to multiple processors, by processing packets for different virtual machines on
different processors.
3.2 Header Data Split
The header-data split feature improves network performance by splitting the headers and data in
received Ethernet frames into separate buffers. The feature is disabled by default and can be
enabled in the Advanced tab (Performance Options) from the Properties window.
