Keywords: PRBS

Discovered in Version: 14.30.1004

Fixed in Release: 14.31.1014

2641734

Description: Fixed the rate select mechanism in QSFP modules.

Keywords: Cables

Discovered in Version: 14.30.1004

Fixed in Release: 14.31.1014

2600783

Description: Fixed classification issues for "Passive" cables to be more robust.

Keywords: Cables

Discovered in Version: 14.30.1004

Fixed in Release: 14.31.1014

2391109

Description: Fixed an issue that caused a fatal error, and eventually resulted in the HCA hanging when a packet was larger than a strided receive WQE that was being scattered.

Keywords: Strided RQ, MTU

Discovered in Version: 14.30.1004

Fixed in Release: 14.31.1014

2621704

Description: Fixed the resource number size (a 64 bit number) to avoid a scenario where it overwrote it with a 32 bit number and erased the high bits when de-allocating the resource number.

In this scenario, when two resource numbers had identical low 32 bits, and because the high bits were cleared, it resulted in the same idx. Consequently, when two idxes were identical, then it freed the same idx twice.

Keywords: Resource number size, free_4k page

Discovered in Version: 14.30.1004

Fixed in Release: 14.31.1014

2619161

Description: Initialized the rate table in the static configuration so it will be configured at the link-not-up scenarios.

Keywords: RoCE, static configuration, rate table

Discovered in Version: 14.30.1004

Fixed in Release: 14.31.1014

2444837

Description: Set the cap to 0 for high index functions to avoid too many parallel VF NODNIC functions.

Keywords: NODNIC, VF, ETH PXE

Discovered in Version: 14.29.1016

Fixed in Release: 14.30.1004

2479788

Keywords: Transport, Rxt Checks

Discovered in Version: 14.29.1016

Fixed in Release: 14.30.1004

2379573

Description: Low performance might be experienced when upgrading from previous firmware version to 14.29.1000 when using “Fast FW Reset”.

Keywords: “Fast FW Reset”, performance

Discovered in Version: 14.29.1016

Fixed in Release: 14.29.2002

Keywords: Congestion Control

Discovered in Version: 14.29.1016

Fixed in Release: 14.29.2002

2339971

Fixed in Release: 14.29.2002

2410395

Description: Fixed an issue that prevented a SFP28 cable from linking up in a 25GbE speed.

Keywords: Cables

Discovered in Version: 14.29.1016

Fixed in Release: 14.29.2002

2093381

Description: Modified the calculation of NUM_VF_MSIX to take into account NVME, Virtio Net/Blk, HotPlug PFs & VFs. Since max_total_msix is the maximum number used for all PFs and VFs (Port, NVME. Virtio Net/Blk, HotPlug), if there are not enough MSIX for all the devices, the number of port VF MSIX may be lowered (less than NUM_VF_MSIX) in order to not exceed the max_total_msix.

Note: In case of compatibility issues with ab old driver requiring more than 4 MSI-X, you should consider lowering number of PFs/VFs on any of the configurable functions (NVME. Virtio Net/Blk).

Keywords: MSIX

Discovered in Version: 14.29.1016

Fixed in Release: 14.29.2002

2360496

Description: Changed the default value of DCQCN's NP parameter min_time_between_cnps to 4 on all devices to support larger scalability of cluster.

Keywords: RoCE, Congestion control, DCQCN

Discovered in Version: 14.28.1002

Fixed in Release: 14.29.1016

2336284

Description: Fixed an issue that caused packets to drop due to header size issues and/or failing checks. The issue was caused due to a Linux issue that caused VFs to set the wrong header size value in wqe_inline_header_mode input.

Keywords: ETH, VF, Linux VM, DSCP, wqe_inline_header_mode

Discovered in Version: 14.28.1002

Fixed in Release: 14.29.1016
