Changes and New Features
SR-IOV - Virtual Functions (VF) per Port - The maximum Virtual Functions (VF) per port is 127. For further information, see Known Issues.
It is recommended to enable the "above 4G decoding" BIOS setting for features that require a large amount of PCIe resources (e.g., SR-IOV with numerous VFs, PCIe Emulated Switch, Large BAR Requests).
Security Hardening Enhancements: This release contains important reliability improvements and security hardening enhancements. NVIDIA recommends upgrading your devices' firmware to this release to improve the devices’ firmware security and reliability.

Feature/Change |
Description |
|
26.41.1000 |
|
|
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. |
|
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. |
