5 Firmware Changes and New Feature History
Table 14 - Firmware Changes and New Feature History
Firmware Version Description
14.14.1100 • CQE Time Stamping: Keeps track of the creation of a packet. A time-stamping ser-
vice supports assertions of proof that a datum existed before a particular time.
• Priority Flow Control (PFC): Applies pause functionality to specific classes of traf-
fic on the Ethernet link.
• RDMA retransmission counters: Custom port counters provide the user a clear indi-
cation about RDMA send/receive statistics and errors.
• Link Layer Discovery Protocol (LLDP): The Link Layer Discovery Protocol
(LLDP) is a vendor-neutral Link Layer protocol in the Internet Protocol Suite used by
network devices for advertising their identity, capabilities, and neighbors on a IEEE
802 LAN. The protocol is formally defined in IEEE 802.1AB.
• 1GbE Link Speed: ConnectX-4 Lx adapters now support 1Gb/s Ethernet connectiv-
ity in addition to 10GigE, 25GigE, 40GigE, 50GigE
• Flow Steering Counters: Provides a clear indication of Flow Steering statistics and
errors.
• WQE Inline Header: The minimal amount of packet headers inlined in the WQE's
Eth Segment.
• table-miss Flow: A flow table may include a table-miss flow entry, which
renders all Match Fields wildcards. If a packet does not match a flow entry in
a flow table, this is a table miss. The behavior on a table miss depends on the
table configuration. A table-miss flow entry in the flow table may specify how
to process unmatched packets.
• Strided WQE User Space: Striding RQ is a receive queue comprised by work queue
elements (i.e. WQEs), where multiple packets of LRO segments (i.e. message) are
written to the same WQE.
• SR-IOV (EN eSwitch & RoCE): Single Root IO Virtualization (SR-IOV) is a tech-
nology that allows a physical PCIe device to present itself multiple times through the
PCIe bus.
• Vector Calculation/Erasure Coding Offload: Uses the HCA for offloading erasure
coding calculations.
• Firmware Image Time Stamping for Multihost Environment: Enables the admin-
istrator to add a timestamp to the firmware they want to upgrade to avoid situations
where one host tries to upgrade the firmware and another tries to downgrade; which
may lead to two or more unnecessary server reboots.
For further information, please refer to MFT User Manual.
• Link params modification via access registers: The change includes the following:
• Changed port configuration which required link re-training (such as speed)
• PAOS down
• PAOS up
This change, will cause the link to toggle and new configurations to take effect.
• Checksum Calculation on Image/Device: Flint utility allows performing an MD5
checksum on the non-persistent sections of the firmware image.
For further information, please refer to MFT User Manual.
14.12.1240
• See Section 4, “Bug Fixes History”, on page 19
14.12.1100 • Reduced the port link-up time when negotiating according to Clause 73 (DME)
