Changes and New Feature in this Firmware Version
| Feature/Change | Description |
|---|---|
14.31.1014 | |
| Using NC-SI Commands for Debugging PCI Link Failures | Implemented a new NC-SI command get_debug_info to get mstdump via the NC-SI protocol to debug a device if the PCI link fails for any given reason. |
| Enable/Disable RDMA via the UEFI HII System Settings | Added support for Enabling/Disabling NIC and RDMA (port/partition) via the UEFI HII system settings. Note: Values set in this option only take effect when is Ethernet mode. |
| Increased the Maximum Number of MSIX per VF | Increased the maximum number of MSIX per VF to 127. Note that increasing the number of MSIX per VF (NUM_VF_MSIX) affects the configured number of VFs (NUM_OF_VFS). The firmware may reduce the configured number of MSIX per VF and/or the number of VFs with respect to maximum number of MSIX vectors supported by the device (MAX_TOTAL_MSIX). |
| Adaptive Routing (AR): multi_path, data_in_order | Added a new bit ("data_in_order") to query the QP and allow a process/library to detect when the AR is enabled. |
| flex_parser for GENEVE Hardware Offload and ICMP | Added a new flex parser to support GENEVE hardware offload and ICMP. |
| Non-Page-Supplier-FLR | When the non-page-supplier-FLR funcion is initiated, the firmware triggers a page event to the page supplier to indicate that all pages should be returned for the FLR function. Pages are returned by the driver to the kernel without issuing the MANAGE_PAGES commands to the firmare. |
