MST_FLAGS
Provide mst flags to be used when invoking mst restart step. For example:--
mst_flags="--with_fpga"
-y|--yes Answer “yes” on prompt
--skip_driver| -s Skip driver start/stop stage (driver must be stopped manually)
-v|--version Print tool version
-h|--help Show help message and exit
--skip_fsm_sync Skip fsm syncing
q|query Query for reset level required to load new firmware
r|reset Execute reset Level
reset_fsm_register Reset the fsm sync register to idle state
Reset Levels and Types
Reset levels and types depend on the extent of the changes introduced when updating the
device'sfirmware. The tool will display the supported reset levels and types that will ensure the loading
of the newfirmware. Those reset levels and types are:
Reset-levels:
0: Driver, PCI link, network link will remain up ("live-Patch")
3: Driver restart and PCI reset
4: Warm Reboot
5: Cold Reboot
Reset-types (relevant only for reset-levels 3,4):
0: Full chip reset
1: Phy-less reset ("port-alive" - network link will remain up)
mstfwreset for Multi-Host NICs
mstfwreset supports a Multi-Host setup. To reset the firmware for a device in a Multi-Host setup,you
have to run the tool on all the hosts simultaneously. The tool utilizes a synchronizationmechanism
supported by the firmware in order to synchronize between the different runninginstances of the tool
on the hosts.
For debugging purposes, it is possible to avoid the synchronization by running the tool with theflag --
skip_fsm_sync.
mstfwreset for Socket-Direct NICs
To reset the firmware on a socket-direct NIC, run the tool on all PCI devices related to the same NIC
with function 0 simultaneously.
See the following example on a Linux OSs:
Exact reset level and types needed to load new firmware may differ, as it depends on the
difference between the running firmware and the firmware we are upgrading to.

When running mstfwreset on a Multi-Host setup, a time-out of 3 minutes is expected for
allthe hosts until they join the firmware reset process.
