Changes and New Feature History

Warning

This section includes history of changes and new feature of 3 major releases back. For older releases history, please refer to the relevant firmware versions.

Feature/Change

Description

26.35.3006

PCC Algorithm

Enables the users to collect more information from NP to RP for PCC algorithm. To achieve this, the NP ingress bytes information was added to the RTT response packet sent from the NP side.

HPCC: Support per-IP and per-QP Methods

Enables the user to configure the PCC algorithm shaper coalescing mode using nvconfig to select CC algorithm shaper coalescing for IB and ROCE.

The new parameters are IB_CC_SHAPER_COALESCE and ROCE_CC_SHAPER_COALESCE.

Bug Fixes

See Bug Fixes in this Firmware Version section.

Feature/Change

Description

26.35.1012

UDP

Added support for copy modify header steering action to/from the UDP field.

Resource Dump

Added the following resource dump segments:

  • SEG_HW_STE_FULL that includes dump to STE and all its dependencies

  • SEG_FW_STE_FULL that include dump to FW_STE and to HW_STE_FULL in range

Striding WQE - Headroom and Tail-room

As the software requires additional space before and after a packet is scattered for its processing for stridden RQ, the hardware will allocate the required room while scattering packets to spare a copy.

QoS Priority Trust Default State

QoS priority trust default state can now be changed using the new nvconfig below:

  • QOS_TRUST_STATE_P1

  • QOS_TRUST_STATE_P2

The values that can be used to set the default state are:

  • TRUST_PORT

  • TRUST_PCP

  • TRUST_DSCP

  • TRUST_DSCP_PCP

26.34.1002

LLDP Properties Implementation on RDE

Added LLDPEnable, LLDPTransmit and LLDPReceive properties to the RDE Port schema implementation.

Programmable CC, PPCC, MAD, IBCC

Added support for PPCC register with bulk operations, MAD for algorithm configuration and tunable parameters.

Programmable Counters

Added support for programmable counters for PCC via PPCC register and MAD.

Congestion Control, PCC

Added Programmable Congestion Control (PCC) support.

Note: User programmability is currently not supported.

Bug Fixes

26.33.1048

MADs

Added a new MAD of class SMP that has the attributes hierarchy_Info as defined in the IB Specification and is used to query the hierarchy information stored on the node and the physical port.

NV Configurations via the Relevant Reset Flow

Added pci_rescan_needed field to the MFRL access register to indicate whether a PCI rescan is needed based on the NV configurations issued by the software.

Note: If the Keep Link Up NV configuration is changed, phyless reset will be blocked.

VF Migration

Added support for VF migration. The hypervisor can now suspend its VF, meaning from that point the VF cannot perform action such as send/receive traffic or run any command. In this firmware version only the suspend resume mode is supported (on the same VM).

VF Migration

Added support for VF migration.

ICM Pages

Added a new register (vhca_icm_ctrl access_reg) to enable querying and limiting the ICM pages in use.

XRQ QP Errors Enhancements

Enhanced the XRQ QP error information provided to the user in case QP goes into an error state. In such case, QUERY_QP will provide information on the syndrome type and which side caused

the error.

ibstat

Updated the ibstat status reported when the phy link is down. Now QUERY_VPORT_STATE.max_tx_speed of UPLINK will not be reported as 0 anymore.

NetworkPort Schema Replacement

Replaced the deprecated NetworkPort schema with Port schema in NIC RDE implementation.

SW Steering Cache

Modified the TX or RX cache invalidation behavior. TX or RX cache invalidation now does not occur automatically but only when the software performs the sync operation using the using sync_steering command.

Firmware Steering

Enabled the option to modify the ip_ecn field in the packet header in firmware steering.

Mega Allocations in Bulk Allocator Mechanism

Modified the maximum bulk size per single allocation from "log_table_size - log_num_unisizes", to allocate any range size, to remove limitations that HWS objects such as counters and modify arguments might encounter.
