The new command should test the rte_dev one. As Thomas pointed out, the etherdev one deals only with eth ports, while hotplug could be generalized to other devices, such as cryptodev. > perhaps it can be good to keep "attach", "detach" keywords for device to > be consistent? > > "device attach #name" > "device detach #name" > I made a point of naming the hotplug operations in rte_bus plug/unplug to avoid the confusion with the etherdev API. hotplug_add / hotplug_remove also marks the distinction. I don't know if it would be helpful for a developer writing a PMD, searching for a way to test a functionality to have an API name mismatch. > Also a show equivalent can be added to work in device level: > "show device info" > I think it would be useful. > > [1] > http://dpdk.org/ml/archives/dev/2017-August/072764.html > > -- Gaëtan Rivet 6WIND
