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 large amount of PCIe resources.
Such features are: SR-IOV with numerous VFs, PCIe Emulated Switch, and 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.
Added a caching mechanism to improved expansion ROM performance and to avoid any slow boot occurrences when loading the expansion ROM driver.
Live Migration Support for Image Size above 4GB
Added support for image size above 4GB when performing a live migration by splitting the image to chunks.
Extended the role-based authentication to cover all crypto algorithms. Now the TLS. IPsec. MACsec. GCM, mem2mem, and NISP work when nv_crypto_conf.crypto_policy = CRYPTO_POLICY_FIPS_LEVEL_2, meaning all cryptographic engines can also work in wrapped mode and not only in plaintext mode.
Programmable Congestion Control
Programmable Congestion Control is now the default CC mechanism. ZTR_RTTCC is the default CC algorithm when ECE is enabled and the CC algorithm negotiation succeeds, otherwise PCC DCQCN will be used.
Added new support for reserved mkey index range. When enabled, a range of mkey indexes is reserved for mkey by name use.
See Bug Fixes in this Firmware Version section.
