mstfwreset Limitations
The following are the limitations of mstfwreset:
Executing a reset level that is lower than the minimal level (as shown in query command) will
yield an error
When burning firmware with mstfwreset at the end of the burn the following message is
displayed:
-I- To load new FW run mstfwreset or reboot machine.
If this message is not displayed, a reboot is required to load a new firmware.
On an old firmware, after a successful reset execution, attempting to query or reset again
will yield an error as the load new firmware command was already sent to the firmware.
In case mstfwreset exits with error after the “Stopping driver” step and before the “Starting
driver” step, the driver will remain down. The user should start the driver manually in this
case.
The new mstfwreset sync capability (–sync) is available only if supported by the firmware and
all the drivers on all the hosts. To check if this is supported, run the "query" command.
mstcongestion – Tool for Setting Congestion Mode and
Action
mstcongestion is a tool used to configure device’s behavior in case of excessive ingress traffic where
the ingress traffic is higher than the PCIe capability. The excessive traffic can either be dropped
(drop action) or marked as CE (Congestion Encountered) in the IP header.
The tool can work in either aggressive mode where traffic is dropped/marked in an aggressive way,
or in dynamic mode where the drop/mark in more relaxed.

When running the reset command without specifying a reset level the minimal reset
level will be performed.
When running the reset command without specifying a reset type the default reset
type would be 0 (Full chip reset).
mstcongestion is not supported in ESXi 7.0.
mstcongestion is supported on ConnectX-4 Lx onwards Multi-Host devices only.
