Mellanox MHGS18-XTC rev.A3 HCA Card Firmware 1.2.000

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
