51 utility is provided for management of the Connect-X 4 and 5 network adapters
52 in the aspects not covered by the generic
54 command, mostly related to the PCIe attachment and internal card working.
55 The utility executes commands on specific adapter, which is addressed using
56 .Em device:bus:slot:function
57 conventions of the PCIe buses.
58 You can match adapters ethernet name and addresses using the
61 The address is passed as an argument of the
63 option, which must be specified for each invocation.
65 When the driver detects the malfunctioning of the hardware, or by user
66 request, it is possible to create
68 which contains debugging information about internal device state, for
69 analysis of the failure by the Mellanox support team.
71 The following commands are currently implemented:
72 .Bl -tag -width indent
74 Take the snapshot of the firmware registers state and store it in the
76 The buffer must be empty, in other words, no dumps should be written so
77 far, or existing dump cleared with the
79 command for the specified device.
81 Clear the stored firmware dump, preparing the kernel buffer for
84 Fetches the stored firmware dump and writes it into the file specified
89 Flashes the firmware image
91 to the specified adapter.
92 Image must be in MFA2 pack format and contain a component suitable
93 for the adapter hardware.
99 node is used to pass commands to the driver.
