Mellanox ConnectX-5 Ex Ethernet Adapter Firmware

Fixes:
- Fixed a PCIe bifurcation issue.
- Fixed a deadlock in RX related to the 'send-invalidate' flow, that resulted in RX getting stuck.
- Fixed rare errors in RX that resulted in double completion.
- Fixed an issue that caused the mlxconfig tool to present all possible expansion ROM images, instead of presenting only the existing images.
- Fixed an issue where modifying VMQoS rate limiter parameters during traffic might cause transmission failure.
- Aligned the default tuning type in PHY TEST MODE to the device protocol.
- Fixed an issue related to PCIe 'Surprise link down' event reporting capability.
- Fixed an issue that resulted in the link partner experiencing false active linkup when plugging in a base-T cable to a closed port.
- Modifying VMQoS rate limiter parameters during traffic might cause transmission failure.


Enhancements:
- Updated MFT4.11
- Added support for an additional layer (Layer 3) of packet processing at the hypervisor level that enables adding and removing protocol headers (e.g., the MAC address is removed during encapsulation, and added during decapsulation) for the encapsulated traffic.
- Enabled QoS ETS for systems with 64 VFs to better allocate bandwidth in the NIC.
- Enabled TTL modification for received packets.
- Mirror the traffic from/to one VF to a dedicate admin VF for monitoring and traffic analysis. Note that in this process packets are duplicated and different packet modifications apply to different duplications.
- Added support for the transmission histogram counter set as part of the Ethernet extended group counters.
- Enabled the hardware to generate an event upon counter incrementation, inorder to reduce an overhead from the software from reading rarely updatedcounters such as error counters.
- Enable NOIDNIC connectivity to the network through the e-switch and not directly to the physical port.
- Enabled setting the QP and the Mkey values by the software upon these resources creation.
- Enabled advanced PCIe atomic operations. The HCA will perform PCIe atomic operations as a requestor towards the host memory when receiving compatible atomic messages from the network, and according to the configuration of NV_SW_OFFLOAD_CONFIG pci_atomic_mode field and the PCI AtomicOp Requester Enable bit in the Device Control 2 register.
- Enabled TTL modification in the Rx NIC steering. When modifying the TTL in the Rx NIC, the CQE checksum will not recalculated automatically.
Note: TTL modification in the FDB for traffic from the network is currently not supported.
- Enabled a single TIR destination from the FDB.
- Changed the WRED default mode to OFF for Multi-Host adapter cards.
- Added support for TX steering rule on flow_table_metadata in WQE Ethernet segment.
- Added L3 encapsulation/decapsulation support in the reformat context allocation.
- L3 encapsulation removes L2 headers and adds generic L3 tunnel encapsulation.
- L3 decapsulation removes the generic L3 tunnel decapsulation and L2 header.
- Added support for flow steering header modification (header rewrite) for IPv4 TTL header for loopback traffic (VF-VF/VF-PF).
Note: TTL modification for traffic from the network is currently not supported.
- Enabled Virtual Functions to read QPDPM/QPDP/QPTS.
- Added support for requester QP packet based on E2E credits mode. The new flow control supports HCA-to-switch RDMA traffic packet-based End-2-End.
- Enable the user to expose two PCI/IB devices per network port.
