Issue

4774394 / 4890471 / 4890472 / 4890473

Description: Fixed an issue where vDPA doorbell resources were not released, which could cause failures when running other functionality after a vDPA FLR. Doorbell resources are now properly unlocked.

Keywords: vDPA

Detected in version:

22.48.1000

Fixed in Release:

22.49.1014

4796182

Description: Fixed an issue where the live migration target did not receive a port state change event on the resume VHCA command. The target now generates this event so software that depends on port state is notified of any changes.

Keywords: Live migration

Detected in version:

22.47.1026

Fixed in Release:

22.49.1014

4924450 / 4942300 / 4942302 / 4942304

Description: Fixed an issue in PCC where RDMA traffic could stall at large scale for certain IP and UDP source-port combinations when a PCC user algorithm was active and no CC algorithm was configured in slot 0.

Keywords: PCC, RDMA

Detected in version:

22.47.1026

Issue

4621747 / 4792742 / 4794290

Description: Fixed an issue where parallel accesses to the MCIA register could return incorrect data. In some hosts running ethtool -m <interface> repeatedly (e.g., once per second), this could intermittently report Identifier: 0x00 (unknown/no module), causing health checks to fail.

Keywords: MCIA register

Detected in version:

22.47.1026

Fixed in Release:

22.48.1000

4727303 / 4718947

Description: Fixed an issue in the steering definers used for LAG with IPv6 traffic.

Keywords: LAG, IPv6 traffic, steering

Detected in version:

22.47.1026

Fixed in Release: 

22.48.1000

4450570 / 4780432 / 4780433

Description: Fixed an issue where the root complex sent MCTP-over-PCI messages before a BDF was assigned, causing responses to be sent with BDF 0. The fix ensures that MCTP messages routed by ID are ignored until a valid BDF is assigned.

Keywords: MCTP-over-PCI, BDF, MCTP messages

Detected in version:

22.47.1026

Fixed in Release: 

22.48.1000

Issue

4575696

Description: Fixed an issue where multiple long-running process registers could cause aborted access and timeouts, the internal state is now properly handled.

Keywords: ibdiagnet2

Detected in version:

22.46.1006

Fixed in Release:

22.47.1026

4501554

Description: Fixed an assertion failure that could occur with the E-Switch uplink in specific configurations where the e-switch was disabled and Path Migration was active or GVMIs were using SRQ loopback in SQs. The issue occurred because the firmware attempted to perform cleanup operations when the uplink configuration lacked sufficient capacity.
Now, when the E-Switch is disabled and no actions are available in the uplink STE, the firmware connects to the uplink STE instead of copying it.

Keywords: Path migration, steering

Detected in version:

22.46.1006

Fixed in Release: 

22.47.1026

4531675

Description: Fixed an incorrect GPIO indication in the INI file that caused a false signal, preventing module initialization.

Keywords: GPIO indication

Detected in version:

22.45.1020

Fixed in Release:

22.47.1026

4529293

Description: Fixed an issue where, during failover or restart, the SM sending a PortInfo MAD to the HCA firmware triggered reinitialization of port buffers, momentarily halting ingress traffic and causing packet drops.
The firmware now avoids reconfiguring port buffers when the new configuration matches the current one.

Keywords: OpenSM

Detected in version:

22.45.1020

Fixed in Release:

22.47.1026

Internal Ref.

Issue

4366117

Description: Configuring a small MTU leads to fragmentation of packets critical for the PXE boot process. As a result, the PXE boot filters mistakenly discard these packets, causing the PXE boot to fail. 

Keywords: PXE boot filters

Discovered in Version:

22.45.1020

Fixed in Release:

22.46.1006
