Fixed in Release:

40.47.3576

5043581 / 4666196

Description: Fixed a PCIe switch initialization issue where upstream traffic was dropped due to ambiguous hardware routing on uninitialized downstream ports, causing downstream devices to disappear from the host.

Keywords: PCIe switch initialization

Detected in version:

40.47.2682

Fixed in Release:

40.47.3576

4970550 / 4843342

Description: Fixed an issue where one-to-one RoCE traffic using a single QP might not achieve line rate on some platforms when using the default ROCE_CC_COMPATIBILITY_MODE setting in mlxconfig.

Keywords: Congestion control, PCC, ROCE_CC_COMPATIBILITY_MODE

Detected in version:

40.46.3004

Fixed in Release:

40.47.3576

4934268 / 4867111

Description: Fixed an issue where RoCEv2 TX traffic could be dropped when running the DOCA spcx_cc application due to stale PCC steering extension entries.

Keywords: spcx_cc cc_steering_ext

Detected in version:

40.47.1026

Fixed in Release:

40.47.3576

4982511 / 4947006

Description: Fixed two rare race conditions in the PCC steering extension when the feature is enabled via path migration, empty RTT, or a custom header.

Keywords: PCC steering extension

Detected in version:

40.47.1026

Fixed in Release:

40.47.3576

5071700 / 4928046

Description: Fixed a corner-case race condition triggered by DSP resets, causing the link to hang.

Keywords: DSP reset

Detected in version:

40.47.1088

Fixed in Release:

40.47.3576

4850603 / 4907678

Description: Fixed a rare race condition in the SUSPEND_VHCA command that could cause the command to hang.

Keywords: Live Migration

Detected in version:

40.47.1088

Fixed in Release:

40.47.3576

4986774 / 4774410

Description: Fixed an issue where the LAG layer steering table had only one strict-SQ entry, causing strict no-port-select traffic to be routed to a single default port. With LOAD_BALANCE_MODE_P1=3, this could lead to link flapping because LACP packets were transmitted only from that default port. The fix expands the LAG layer steering table and adds additional strict-port entries to distribute strict traffic correctly.

Keywords: Link Flapping

Detected in version:

40.47.1026

Fixed in Release:

40.47.3576
