Changes and New Features

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.
