160 | .SS devlink dev info - display device information. |
161 | Display device information provided by the driver. This command can be used | |
162 | to query versions of the hardware components or device components which | |
163 | can't be updated ( | |
164 | .I fixed | |
165 | ) as well as device firmware which can be updated. For firmware components | |
166 | .I running | |
167 | displays the versions of firmware currently loaded into the device, while | |
168 | .I stored | |
169 | reports the versions in device's flash. | |
