Issue

2641734

Description: Fixed the rate select mechanism in QSFP modules.

Keywords: Cables

Discovered in Version: 26.30.1004

Fixed in Release: 26.31.1014

2403501

Description: Fixed an issue that caused the firmware to return a wrong value in "port_buffer_size" field of PBMC access register.

Keywords: Access register, PBMC

Discovered in Version: 26.30.1004

Fixed in Release: 26.31.1014

2600783

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

Keywords: Cables

Discovered in Version: 26.30.1004

Fixed in Release: 26.31.1014

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: 26.30.1004

Fixed in Release: 26.31.1014

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: 26.30.1004

Fixed in Release: 26.31.1014

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: 26.30.1004

Fixed in Release: 26.31.1014

Fixed in Release: 26.29.2002

2410395

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

Keywords: Cables

Discovered in Version: 22.29.1016

Fixed in Release: 26.29.2002

2385117

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: 22.29.1016

Fixed in Release: 26.29.2002

2199939
