Changes and New Feature in this Firmware Version

Feature/Change

Description

24.37.1300

Precision Time Protocol (PTP)

Added support for Precision Time Protocol (PTP), the protocol used to synchronize clocks throughout a computer network as part of 5T Technology.

Mergeable Buffer

Added mergeable buffer support (VIRTIO_NET_F_MRG_RXBUF in virtio spec) for VDPA kernel mode to improve performance in case of large MTU such as 9K. The feature is disabled by default and must be manually enabled while creating or modifying the virtio device.

Note: For best performance, it is NOT recommended to enable the feature if the VDPA MTU is set to the default value (1500).

Monitoring Cloud Guest RoCE Statistics on Cloud Provider

This new capability enables the VM to track and limit its Vport's activity. This is done using the new q_counters counter which enables aggregation of other Vport's from PF GVMI.

NVME Device Emulation

Enables the firmware to generate a Device Change Event upon any change in the NVME Device Emulation object (BAR change, HotPlug power state change, NVME Function reset, etc).

PCC Algorithms

Enables a smooth and statically switch between PCC algorithms. In addition, the user can now switch between PCC algorithms while running traffic.

Hardware Steering: Bulk Allocation

Added support for 32 actions in the header modify pattern using bulk allocation.
