SR-IOV uses IOMMU functionality to translate PCIe virtual addresses to physical addresses by using a translation table.
The number of Physical Functions (PFs) and Virtual Functions (VFs) are managed through the UEFI HII menu, the CCM,
and through NVRAM configurations. SR-IOV can be supported in combination with NPAR mode.
The SR-IOV feature requires corresponding SR-IOV support in the BIOS (Intel VT-d or AMD IOMMU) and Operating System/
Hypervisor as well as the PCIe endpoint device (the NIC in this case).
The NetXtreme-E family of Ethernet Controllers offers the following offload functionality to the VF that are available to the PF:
TX and RX IP/TCP/UDP checksum offload
Large Send offload (LSO) or TCP segmentation offload (TSO, GSO)
Receive Segmentation offload (RSC) or Large Receive offload (LRO, GRO)
Receive Side Scaling (RSS) – up to 64 queues per VF
Multiple COS queues – up to 4 queues per VF
