Mellanox MHGS18-XTC rev.A4 HCA Card Firmware 1.2.000 Description

New Features:

- Improved multi-core latency
- Added the ability to configure the PCI Express Ack Latency Timer via the firmware INI file.
- Added the ability to configure the PCI Express SerDes via the firmware INI file.

Bug Fixes:

- msg_hdr_size is wrong
- Suspend QP may cause corruption of CmdIf and/or QP context corruption
- While a link is in the DDR Auto-negotiation process, it may report a POLLING state for the physical link and an INITIALIZE state for the logical link while it should report POLLING and LinkDown, respectively
- Slow handling of Out-of-Sequence packets following RNR Nack may cause back-pressure
- PCI Express bit relaxed_ordering_en is R/W instead of Read Only
- Sending MSIX interrupt messages may cause a deadlock in a heavy-stress condition
- If the command QUERY_FW is run before the command RUN_FW, the returned QUERY_FW dt (Debug Trace) bit is returned with the wrong value
- The first WQE can be posted to any random location in the WQE buffer. FW fails if this location is not the first.
- FW may fail (FW_INTERNAL_ERROR) upon large stress
- The minimum acceptable Local_ACK_Timeout parameter was changed from 0xC to 0xD to reduce unnecessary timeouts

Changes:

- Newer versions of Tiger/Cheetah HCA cards have a single 2MByte Flash device. In case Debug FW is burnt onto this Flash device, access to addresses equal to or higher than 1MByte fail

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
