Internal Ref.

Issue

4321324

Description: Fixed an issue in SD where sending an ATS translation address request could lead to a completion timeout.

Keywords: PCI

Detected in version: 40.44.0208

Fixed in Release: 40.45.1020

4318537

Description: Fixed an issue where the AI and HAI parameters of the ZTR_RTTCC algorithm, when configured by users, were automatically overwritten upon link speed changes. With this fix, if AI/HAI values were tuned for link speeds other than 100Gb/s, users should now divide those values by (link_speed / 100) to maintain consistent congestion control algorithm behavior.

Keywords: Congestion control, ZTR_RTTCC

Detected in version: 40.44.0208

Fixed in Release: 40.45.1020

Description: Although ConnectX-8 SuperNIC is defined to work at Gen6 x16 (default) or Gen5 x32, in firmware v40.44.0204, the default configuration is Gen5 x32. Changing between the modes is done by an NVConfig command.

Keywords: Gen6, Gen5, PCIe

Detected in version: 40.44.0208

Fixed in Release: 40.45.1020

4158184

Description: The Lane Error Status may occasionally appear in Configuration space. It can be safely ignored as it does not have any impact on device performance. Users are encouraged to monitor their systems, but this condition does not warrant any immediate action unless other issues arise.

Keywords: Lane Error Status

Detected in version: 40.44.0208

Fixed in Release: 40.45.1020

4274669

Description: Fixed a race condition that could prevent the application from transmitting when VQoS is enabled.

Keywords: Firmware assert

Detected in version: 40.44.1036

Fixed in Release: 40.45.1020

4268027
