I am suspicious on adding new root level command to testpmd, it is
getting bigger, each command looks OK on its own context, but as a whole
app getting more confusing [1].

Since dealing with device is kind of new, it can be OK to create new
command tree, but there are already hotplug commands per port:
"port attach #PCI|#VDEV_NAME"
"port detach #P"

perhaps it can be good to keep "attach", "detach" keywords for device to
be consistent?

"device attach #name"
"device detach #name"

Also a show equivalent can be added to work in device level:
"show device info"
