Discovered in Version: 24.38.1002

Fixed in Release: 24.39.2048

3629353

Description: Fixed the cr_space in port configuration to prevent wrong timestamp of cqes.

Keywords: Hardware timestamp

Discovered in Version: 24.38.1002

Fixed in Release: 24.39.2048

3547022

Description: Fixed an issue that resulted in reset failure when unloading network drivers on an external host and the sync1 reset is still reported as 'supported' although it is not.

Keywords: sync1 reset

Discovered in Version: 24.38.1002

Fixed in Release: 24.39.2048

3534774

Description: Fixed an issue that prevented the Power Controller Control bit in the Slot Control register from returning to default when forcing the Unplug sequence.

Keywords: Power Controller Control

Discovered in Version: 24.38.1002

Fixed in Release: 24.39.2048

3602169

Description: Added a locking mechanism to protect the firmware from a race condition between insertion and deletion of the same rule in parallel which occasionally resulted in firmware accessing a memory that has already been released, thus causing IOMMU / translation error.

Note: This fix will not impact insertion rate for tables owned by SW steering.

Keywords: Firmware steering

Discovered in Version: 24.38.1002

Fixed in Release: 24.39.2048

3612682

Description: Enabled live migration for virtio with mergeable buffer.

Keywords: Virtio, Mergeable buffer, Live migration

Discovered in Version: 24.38.1002

Fixed in Release: 24.39.2048

3571251

Description: Fixed an issue that resulted in migration data corruption when running parallel save_vhca_state/load_vhca_state commands on the same PF.

Keywords: VF live migration

Discovered in Version: 24.38.1002

Fixed in Release: 24.39.2048

Issue

3365411

Description: Fixed a link failure that occurred due to a wrong 'is_inphi_cable' indication.

Keywords: Link failure

Discovered in Version: 24.37.1300

Fixed in Release: 24.38.1002

3435583

Description: Under certain configurations, during the loading of the PXE driver in Smart-NIC mode, the firmware attempts to lock the CMAS resources in ICMC sets that are full. This results in the failure of the locking and raises a health buffer indication.

To prevent the above scenario, in this firmware version we improved the distribution of resource locking in ICMC.

Keywords: ICMC locking

Discovered in Version: 24.37.1300

Fixed in Release: 24.38.1002

3331179

Description: Improved token calculation.

Keywords: Token calculation

Discovered in Version: 24.37.1300

Fixed in Release: 24.38.1002

3491841

Description: Fixed a firmware assert that occurred when tried to verify if the module supported "swap".

Keywords: Firmware assert
