Changes and New Feature History

Note

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
26.35.3502
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	See 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.
