Changes and New Feature History

Memory Slow Release

Added a new command interface "Memory slow release" to enable/disable holding memory pages for a defined period of time. Once the timer expires, the firmware will return the pages to the driver.

Kernel Lockdown

Added support for MVTS register via a miscellaneous driver using the access_register PRM command.

Steering SF Traffic to a Specific PF MSI-X

MSI-X on SF can be received now through the PF's MSI-X vector.

Unify Rx/Tx Table Domains in FDB

The new unified_fdb subdomain simplifies the FDB model by eliminating the need to duplicate rules for RX and TX tables. This domain is directionless, meaning no RX/TX specific actions are allowed. Firmware now handlea packet transitions IN and OUT of the unified domain, allowing for a more streamlined packet flow management.

Software can now transition between unified_fdb and FDB_RX/FDB_TX domains as long as the packet maintains the same direction, without the risk of dropping the packet when crossing between RX and TX.

TRNG FIPS Compliance

Implemented Deterministic Random Bit Generator (DRBG) algorithm on top of firmware TRNG (the source for raw data input) in accordance with NIST SP800-90A.

vDPA Live Migration

Added support for vDPA virtual queue state change from suspend to ready, and discrete mkey for descriptor. vDPA Live Migration uses these two new capabilities to reduce downtime since vq can go back to ready state for traffic and descriptor-only-mkey can help reduce mkey mapping time.

64M Active Connections

Added the ability to generate up to 2^30 STE objects through the general object creation command.

NVConfig

Added a new NVConfig option to copy AR bit from the BTH header to the DHCP header.

Steering

Added the option provide field's offset and length in Steering add_action option.

Steering Match

Added support for steering match on packet l4_type through FTG/FTE.

Flex Parser Merge Mechanism

Extended Flex Parser merge mechanism to support hardware capabilities.

Flex Parser

Enabled the option to disable the native parser when the parse graph node is configured with the same conditions.

Flex Parser

Added support for father/son headers parsing.

LRO

Added support for tunnel_offload in LRO.

Socket Direct Single netdev Mapped to Two PCIe Devices

Enabled Single Netdev mapping to two PCIe devices (Socket Direct).

Now multiple devices (PFs) of the same port can be combined under a single netdev instance. Traffic is passed through different devices belonging to different NUMA sockets, thus saving cross-NUMA traffic and allowing apps running on the same netdev from different NUMAs to still feel a sense of proximity to the device and achieve improved performance.

The netdev is destroyed once any of the PFs is removed. A proper configuration would utilize the correct close NUMA when working on a certain app/CPU.

Currently, this capability is limited to PFs only, and up to two devices (sockets). To enable the feature, one must configure the same Socket Direct group (non zero) for both PFs through mlxconfig SD_GROUP.

ACL

Added support for egress ACL to the uplink by adding a new bit to the Set Flow Table Entry: allow_fdb_uplink_hairpin.
