Changes and New Features

Header Modification

Added support to the metadata reg_c 8-11 (packet fields) for matching and modifying the header, and Advanced Steering Operation (ASO) actions.

INT Packets

Added support for forwarding INT packets to the user application for monitoring purposes by matching the BTH acknowledge request bit (bth_a).

Get Electrical Sensor, NC-SI

Implemented NVIDIA NC-SI OEM Commands:

• Get Electrical Sensor Count (command 0x13, parameter 0x6)

• Gel Electrical Sensor (command 0x13, parameter 0x7)

• Get Electrical Sensors (command 0x13, parameter 0x8)

IPsec CPS Bulk Allocation

Improved the IPsec CPS by using bulk allocation.

For cases in which log_obj_range == 0, single IPSEC object will be allocated and initialized as before keeping backward compatibility.

For better performance, it is recommended to work with IPsec bulk allocation and to initialize IPsec ASO context not via the firmware but via the hardware using ASO WQE.

DPA PROCESS ERROR

Added support for a new value for coredump_type field in DPA_PROCESS_COREDUMP, [FIRST_ERROR_THREAD_DUMP (1).].

TX Settings

Modified SERDES TX settings.

Out-of-Order (OOO)

Out-of-Order (OOO) re-orders packets that arrive out-of-order to consume them.

Firmware Content

Moved from the ‘light firmware’ branch in the Multi Host OPNs to a the main firmware branch (full firmware). 

QKEY Mitigation in the Kernel

Limited QKEY creation with the MSB set only to privileged users.
