4878440 / 4834414

Description: Fixed an issue on RHEL systems where installing chkconfig after mlnx-ofa_kernel (pulled in by packages such as doca-ofed and doca-host) could fail during installation. In this sequence, chkconfig may be installed indirectly as a dependency of a package that places init scripts under /etc/init.d, but the install would error out because /etc/init.d already existed as a directory (whereas chkconfig expects to manage it as a symlink). This fix prevents the /etc/init.d directory/symlink conflict that caused the RPM unpacking failure.

Keyword: Installation

Reported in version: 3.2.1

4845289 / 4848666 / 4851349 / 4857860 / NVBug 5825913

Keyword: DOCA-Host compilation 

Reported in version: 3.2.1

4830937 / 4775049 / 4865514

Description: Fixed an issue where the driver could incorrectly initialize polling-only CQs (e.g., ASO CQs), allowing them to receive EQ interrupts in rare cases. The CQ initialization flow was updated to prevent interrupts for polling-only CQs.

Keyword: mlnx-ofa_kernel DKMS package upgrade

Reported in version: 3.2.1

4878487 / 4808487

Description: Fixed an issue where, under certain circumstances, upgrading the mlnx-ofa_kernel DKMS package could cause a submodule package (e.g., iser or srp) to use a leftover build directory from /var/lib/dkms.

Keyword: mlnx-ofa_kernel DKMS package upgrade

Reported in version: 3.2.1

4869510 / 4802194

Description: Fixed an overflow issue where the max-rate value was stored in a unsigned 8-bit integer type, causing values above 255 to wrap (e.g., 257 became 1).

Keyword: max-rate value

Reported in version: 3.2.1

4868130 / 4426799

Description: Fixed an issue where devlink operations were not synchronized with fw_reset, which could lead to various failures. Added a mechanism to coordinate fw_reset with devlink operations.

Keyword: devlink, fw_reset

4858692 / 4858587

Description: Fixed soft lockup warnings that could occur while releasing large UMEMs by periodically yielding the CPU during the release flow.

Keyword: soft lockup warnings

Reported in version: 3.2.1

4789990 / 4778339 / 4776537

Description: Added support for MAC forwarding on the uplink representor for multi-host and DPU environments. This allows the uplink representor to explicitly request MAC address forwarding in MPF configurations, where multiple PFs share a single physical port. The implementation includes proper MAC address lifecycle management using the MPFS table, hardware flow rules, and software hash tables, with automatic cleanup when the driver is unloaded or when the eswitch mode is changed.

Keyword: MAC forwarding, uplink representor, MPFS, DPU

Reported in version: 3.2.1
