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