What is the device name?
I think we should register a callback for a rte_device or NULL (all devices).
please see my v12 patch, the device name have been info to user.
i think a device name for a callback might be fulfill , since if use
NULL for all device, a callback could not belong to a NULL point. if
there are any advantage by callback for a rte_device, please explicit
outline it. and i think it must be a improvement and anyway if need i
will try to make it better.
and what ever a callback for a rte_device or a device name for a
callback, i think that is not our gap, i guess what you care about is
that the new and firstly hot plug in device monitor , so i would add
null check for identify these new device callback. am i right?
