Feature/Change |
Description |
32.43.1014 |
|
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:
The first mode is used to support ZTRCC RX bytes in RTT response. |
HPCC2 Custom Header |
Added support for HPCC2 custom header insertion in RTT request packets for DOCA PCC. The capability will be supported when setting |
Hight Availability for virtio-net-controller |
Added support for a second emulation VirtIO blk and net device on the same vHCA to enable switching to the second emulation device and reduce downtime. |
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: |
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:
The new added caps are:
|
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 |
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. |
Virtual Quality of Service |
Added a new scheduling element type ("TC_ARB") capability in the VQoS domain (Virtual Quality of Service), to support TC arbitration between functions (VPORTs). |
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. |
