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 Offloadand ICMP

Added a new flex parser to support GENEVE hardware offloadand 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.
