Feature/Change	Description
28.43.1014
PCIe Telemetry	Added support for PCIe Telemetry (NSM Type 2).
Programmable Congestion Control (PCC)	Migrated PCC NP solution from ACE hardware platform to DPA hardware platform. The new capability is applicable to the following 2 modes: PCC_INT_EN=True and PCC_INT_NP_RTT_DATA_MODE=INGRESS_BYTE PCC_INT_EN=True and PCC_INT_NP_RTT_DATA_MODE=NO_DATA The first mode is used to support ZTRCC RX bytes in RTT response.
RDMA Telemetry	Added the option to indicate an error CQE event on every selected function per eSwitch manager. This indication is defined as a new WQE including the relevant information about the error (such as: syndrome, function_id, timestamp, QPs num etc.). The feature is configured using a new general object: RDMA-Telemetry object, and depends on the following new caps: `HCA_CAP.rdma_telemetry_notification_types` and `HCA_CAP.rdma_telemetry`.
UID Permissions	Extended kernel lockdown permission set. The following sub-operations can now be called by tools (permission TOOLS_RESORCES) using new HCA capability bitmask field: tool_partial_cap. The 5 sub-operations are: QUERY_HCA_CAP with other function QUERY_VUID with direct data QUERY_ROCE_ADDRESS with other vport SET_HCA_CAP with other function POSTPONE_CONNECTED_QP_TIMEOUT with other vport The new added caps are: tool_partial_cap.postpone_conn_qp_timeout_other_vport, tool_partial_cap.set_hca_cap_other_func tool_partial_cap.query_roce_addr_other_vport tool_partial_cap.query_vuid_direct_data tool_partial_cap.query_hca_cap_other_func
Cross E-Switch Scheduling	Added support for QoS scheduling across multiple E-Switches grouped in a LAG. VPort members of a Physical Function can be added to a rate group from another Physical Function and rate limits of the group will apply to those VPort members as well.
Jump from NIC_TX to FDB_TX	Added `'table_type_valid'` and `'table_type'` fields to the steering action (STC) "Jump To Flow" table parameters to enable the user to jump from NIC_TX to FDB_TX and bypass the ACL table.
Jump to TIR or queue from FDB on Tx	Enabled hop reduction by bypassing NIC domain in various use cases. Such action r educes the number of hops (improves PPS) to deal with mass number of flows and devices. To enable this new capability, a new STC action type "JUMP_TO_FDB_RX" was added to allow jumping into the RX side of a table.
Flex Parser: ARC-IN and ARC-OUT	Increased the maximum number of supported "ARC-IN" from 1 to 8 and "ARC-OUT" from 3 to 8 for the dynamic flex parser.
PSP Crypto Offload	[Alpha] Added support for PSP Crypto offload transport mode.
ZTR_RTTCC Histogram	Added histogram support for rate and Round-Trip Time (RTT) in PCC ZTR_RTTCC.
Bug Fixes	See Bug Fixes in this Firmware Version section.
