57 utility is provided for management of the Connect-X4, 5 and 6 network adapters
58 in the aspects not covered by the generic
60 command, mostly related to the PCIe attachment and internal card working.
61 The utility executes commands on specific adapter, which is addressed using
62 .Em device:bus:slot:function
63 conventions of the PCIe buses.
64 You can match adapters ethernet name and addresses using the
67 The address is passed as an argument of the
69 option, which must be specified for each invocation.
71 When the driver detects the malfunctioning of the hardware, or by user
72 request, it is possible to create
74 which contains debugging information about internal device state, for
75 analysis of the failure by the Mellanox support team.
77 The following commands are currently implemented:
78 .Bl -tag -width indent
80 Print EEPROM information
82 Take the snapshot of the firmware registers state and store it in the
84 The buffer must be empty, in other words, no dumps should be written so
85 far, or existing dump cleared with the
87 Flashes the firmware image
89 to the specified adapter.
90 Image must be in MFA2 pack format and contain a component suitable
91 for the adapter hardware.
93 Typically, PCIe link-level reset is required to activate the
94 newly flashed image, which can be performed by the system reboot
99 command for the specified device.
101 Clear the stored firmware dump, preparing the kernel buffer for
104 Fetches the stored firmware dump and writes it into the file specified
109 Performs PCIe link-level reset on the specified device.
115 node is used to pass commands to the driver.
