sFlow Sampling Rules Offload

[ConnectX-5 and above] Added support for sFlow sampling rules offloads. sFlow is an industry standard technology for monitoring high speed switched networks. Open vSwitch integrated sFlow to extend the visibility into virtual servers, ensuring data center visibility and control.

VLAN Push on RX and Pop on TX

[ConnectX-6 Dx and above] Added support in SwitchDev mode to push VLAN on RX (rules on uplink representor) and pop on TX (rules on VF representor). This feature is only supported in Software Steering mode.

Control SF Class

[All HCAs] Added support for Control SF Class. Each PCI, PF, VF, SF function, by default, has netdevice, RDMA, and vdpa-net devices always enabled. This feature enables the user to control which device functionality to enable/disable.

mlx5 VFIO CQ Interrupt Mode

[ConnectX-5 and above] Added support for mlx5 VFIO CQ interrupt mode. This feature allows applications to listen on and capture CQ complection events via the Event Queue mechanism with mlx5 VFIO driver.

mlx5 VFIO Asynchronous Event

[ConnectX-5 and above] Added support for mlx5 VFIO asynchronous event. This feature supports applications to listen on and capture device asynchronous events via the Event Queue mechanism with mlx5 VFIO driver.

Matching Granularity Change

[ConnectX-5 and above] Added support for matching granularity change. Currently when creating FDB flow with destination of VPORT, a src_port matching must be added. This feature removes that limitation so a FDB flow can match all VPorts and go to a VPORT destination. The new behavior is the same as as that on firmware steering.

Full Tunnel Header Matching

[ConnectX-6 Dx and above] Added support for full tunnel header matching. Currently, the full-tunnel-header matching cannot be used along with many other criteria within one matcher. This feature is to add the support for that by using the new definer index, defined in the firmware, to build matcher so that the full tunnel header matching can be used along with all other criteria.
