Feature/Change | Description |
14.32.1010 | |
Congestion Control Key | Added a Congestion Control Key to all Congestion Control MADs to authenticate that they are originated from a trusted source. |
SMP Firewall | Added an SMP firewall to block the option of sending SMPs (MADS sent on QP0 from the Subnet Manager) from unauthorized hosts to prevent fake SMPs from being recognized as the SM. |
Vendor Specific MADs: Class 0x9 | Vendor Specific MADs Class 0x9 is no longer supported by the firmware. If case the firmware detects such MAD, the firmware will return a “NOT SUPPORTED” error to the user. |
Asserts’ Severity Level | Added 3 new assert filters (Health buffer, NVlog, FW trace). The assert will be exposed now if its severity level is equal to or above the new filter. The filters are configurable by the ini file. The “Health buffer” filter is also configurable by new access register. |
Rate Limit per VM instead of VM-TC | Enabled Rate Limit per VM instead of VM-TC. This capability is implemented by adding support to a new Scheduling element type: rate limit elements that will connect to the rate_limit and will share its rate limit. |
Asymmetrical VFs per PF | Added support for asymmetrical VFs per PF. To enable it: |
mlxlink Support to read/write Access Registers by LID | Added 2 new MAD access registers to enable mlxlink to read/write access registers by LID (to the whole subnet). |
