Sure. You can also use ibstat or ibv_devinfo tool if they are installed. But
it's not very convenient in some cases.

This is the standardised way to do this. It should work for any
Ethernet driver, so long as it fills in the needed information.
Anything else is non-standard, and so inconvenient by definition.
