Issue

2648336

Description: Disabled the CNP counter “rp_cnp_ignored " (triggered by OOS (out-of-sequence)) when all ports are IB.

Note: For mixed IB/ETH scenario, the behavior depends on the RoCE configuration, the counter on the IB port may still increase but will not affect the regular use.

Keywords: CNP counter, IB

Discovered in Version: 20.30.1004

Fixed in Release: 20.31.1014

2178949

Description: Improved PortXmitWait IB counter accuracy.

Keywords: Bandwidth, performance

Discovered in Version: 20.30.1004

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: 20.30.1004

Keywords: RX pipe

Discovered in Version: 20.30.1004

Fixed in Release: 20.31.1014

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: 20.30.1004

Fixed in Release: 20.31.1014

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: 20.29.1016
