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