Feature/Change	Description
24.43.1014
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
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.
Hotplug/Unplug on VirtIO Devices when the Host is Powered OFF	Enabled hotplug/hotunplug during device's power off or power cycle to prevent the device from getting stuck.
2-steps-hotplug	Added support for 2-steps-hotplug capability. The device is plugged with "free" status by default, and it will not appear on the bus until being modified to "hotplug" status.
